Royal Blood have postponed more tour dates due to illness.
The rock duo - made up of Mike Kerr and Ben Thatcher - have been forced to pull out of more shows in mainland Europe after Mike fell ill with "severe tonsilitus".
According to NME, the pair - who previously cancelled shows in Portsmouth, Oxford and Bristol - have now been forced to pull out of gigs in Milan, Barcelona, Lisbon and Madrid, following "medical advice".
They released a statement saying: "Customers are advised to retain their tickets and await further information with regard to rescheduled dates which will be planned and announced as quickly as possible. We wish to sincerely apologise to all ticket holders for the inconvenience and disappointment this has caused."
The band's missed UK tour dates have now been rescheduled for December and early January.
Royal Blood have also signed up to support Foo Fighters during their UK stadium tour next summer.
Foo Fighters frontman Dave Grohl recently admitted he was "genuinely excited" by the band.
He said: "I saw some live footage of them, and I was so excited to see a band that was heavy, had riffs, had songs, and could really perform, and an audience that was genuinely excited to watch them play."

Michael Palin is worried he'll "lose his connection with the past" if he's put into a care home.
The 71-year-old former 'Monty Python' comedian has admitted that playing Tom Patfitt - an 80-year-old man who is forced to live in a nursing home - in the new BBC drama 'Remember Me' has made him think about his own future.
When asked how he would feel if he was forced to live in a care home, Michael responded: "I know that if I was taken away from my home to go and live somewhere else, even if I needed the treatment, a whole part of my life would have gone; my connection with the past and all the objects that I've collected. Keeping people in their own home environment for as long as possible is really important.
"My father was in a home for a bit, and however enlightened the people and friendly the care, I just was aware that he had lost something."
Despite revealing that he is worried about his future residence, the veteran actor explained that he is optimistic that science will make the ageing process easier in years to come.
Talking to Radio Times magazine, he said: "Undoubtedly the years go by, I'm aware that I read the medical pages more carefully, follow the great statins debate and that kind of thing.
"But to be honest, it seems to me my life is much more enjoyable, certainly better organised, now than it was when I was young. I think I have benefited, as I approach my 70s, from the jolts and jars of earlier ages."

Simon Cowell is reportedly sick of Louis Walsh winding people up.
The 'X Factor' boss is said to be questioning Louis' future as a judge after ten years on the ITV talent show because of his affect on fellow mentors Mel B and Cheryl Fernandez-Versini.
A source told Now magazine: "The three judges are barely speaking to Louis right now. Simon's sick of him winding everyone up and tensions have been mounting for weeks.
"Cheryl and Mel keep saying they're not sure they can put up with him for the rest of the series. Simon reminds them they only have until Christmas, but he also finds it hard not to lose his cool over Louis' attitude."
Louis came under fire recently after deciding to take the vote to deadlock, resulting in Paul Akister being sent home, but his feud with Cheryl has been going strong for years.
She said previously: "I accept him for what he is. But he's not someone I'd call tomorrow if I was in a crisis."

Chris Hemsworth learnt how to be "sexy" from Matt Damon.
The 'Avengers' star - who was crowned People magazine's Sexiest Man Alive this year - thanked previous winner Matt, 44, for helping him take home the award.
He told Jimmy Kimmel on his talk show on Tuesday night (18.11.14): "I learned everything there is about being sexy from Matt.
"Thank you Matt and all the other previous intelligent men."
The 31-year-old star - who accepted his award via video during the show - also paid tribute to his parents for giving him his looks and admitted his brother, fellow actor Liam Hemsworth has been very supportive since learning of his new title.
He said: "He's been a real team player for this one. We've been throwing sexy looks back and forth all week."
And when asked who he'd like to thank, Chris said: "My parents, I guess, for putting this together."
The 'Rush' actor - who is married to 'Fast and Furious 6' star Elsa Pataky - recently claimed the award had given him "a couple of weeks of bragging rights" in their house.
Chris - who has India, two, and seven-month-old twins Tristan and Saha with Elsa - said: "I can just say to her, 'Now remember, this is what the people think, so I don't need to do the dishes anymore, I don't need to change nappies. I'm above that. I've made it now."

Evan Ross' marriage to Ashlee Simpson is the "best thing ever".
'The Hunger Games' star - who wed Ashlee in August this year - has revealed the couple are still very much in the honeymoon period following their nuptials and confessed he was eager to get back to the blonde beauty as he chatted on the red carpet at the film's LA premiere earlier this week.
He told US Weekly of his marriage: "It's the best thing ever. I actually want to get back to her, although I'm excited to be on the carpet - it's incredible.
"I've been with her now for a while so it just feels right. I'm happy to say she's my wife."
The 26-year-old actor added he is keen to have kids with Ashlee, 30, who already has a five-year-old son Bronx, with her ex husband Pete Wentz.
He said: "I would love to [have kids]. As many as possible."
Ashlee is said to be equally keen to give a sibling to Bronx, and the pair - who married in a romantic ceremony held at Evan's mother Diana Ross' lavish home in Greenwich, Connecticut, on August 30 - "can't wait" to see their families grow.
A source recently said: "They can't wait [to have a child together]."
While Evan commented: "Now we have two huge families."

Wretch 32 wants to release an album every year.
The 29-year-old rapper's last LP, 'Black and White', came out in 2011 and has his next record 'Growing Over Life' ready to go.
Wretch insists he'd rather not wait and instead he'd be happy to have an annual release, regardless of how many copies it sold.
He exclusively told BANG Showbiz: "Every year I have two hours worth of material which should be two albums, this is my offering to the world, and I feel like every year I don't put one out, I'm not complete as a person because I'm not doing what I'm meant to be doing.
"Everything's got to have this strategy in this day and age. I think everybody's afraid of having an album that sold 200,000 and then doing the next one which doesn't do as well and I never really got into this to be in that frame of mind about sales projections."
The pop star - whose latest single '6 Words' is out now - has even contemplated giving away his music online, but he thinks if he did "leak" his tracks the act itself would overshadow the songs.
When asked whether he'd considered leaking his tracks, he said: "Yeah, many a time but the sad thing about that is it's an injustice because the focus is always more concerned on the word 'leak' than the music.
"It's not on the music, on the album, it's just on the event that's happened because it's shocking to people to hear that. I don't really want to be known for that, that's what always stops me."

Angelina Jolie plans to star in "a few more" movies.
The 39-year-old star, who previously revealed she wants to focus on directing and her humanitarian work in the future, says she isn't ready to retire from the big screen just yet.
Discussing her future acting plans, she said: "I'll do a few more."
But she told Variety magazine that her heart still lies behind the camera, saying: "I'm happier when I get to put a camera on another actor and watch them do great work."
Despite being very passionate about directing, Angelia wasn't instantly handed the job on her new movie, 'Unbroken,' even though Universal Pictures chairman Donna Langley was a fan of her 2011 directorial debut 'The Land of Blood and Honey'.
Langley said: "I've seen almost every film about that conflict, and I thought her film was the most impactful and clearest about what people were living through during that time. The movie follows the story of a woman caught in difficult circumstances, who has to persevere; that's very synonymous with Louis Zamperini's story [in 'Unbroken']."
But she added: "She had to work for it. I put her through her paces."
The brunette beauty created a picture board representing her vision for scenes and characters in the project in a bid to secure the opportunity.
Langley said: "After a few conversations, it became very clear that she was ready to step up to the task."

Lorde says her mother stops her from becoming a diva.
The 18-year-old singer has achieved worldwide global pop success since the release of her debut album 'Pure Heroine' last year but she still travels everywhere with her mum, poet Sonja Yelich, and she puts a stop to any histrionics straight away.
She revealed: "I live at home, in my childhood bedroom. I travel with my mum and if I were to ever say anything a little bit diva-esque, she'd knock it right down."
Although she has achieved her musical dreams at a young age, Lorde still enjoys living the life of a regular teenager and as soon as she gets home to Takapuna in Auckland, New Zealand, she reconnects with her friends.
And her pals love to mercilessly tease her about her pop star status.
The 'Royals' singer - who has just compiled the soundtrack for 'The Hunger Games: Mockingjay - Part 1' - told Time Out magazine: "It's important to me that I'm still in touch with my teenage life, even if what I'm doing every day may not be strictly teenage. So the second I get home I'm calling my friends. I love being young and I want to retain that for as long as possible, even if I am like an old lady and working all the time.
"My friends all tease me. We'll go out and get food, and without fail one of them will say, really loud, 'Oh my god! Is that Lorde?' It's so horrible, but they're great."

Mel C is too scared to join Tinder.
The 40-year-old star - whose full name is Melanie Chisholm - refuses to comment on whether or not she currently has a boyfriend but insists she's far too scared to use online dating services.
Speaking about trying out the app on her friend's phone, she said: "I've never been able to do Tinder, so I was like, 'I really wanna have a go - I feel left out!' So we started messaging some hunky guy. It's going well - we found her a winner!"
Quizzed on whether she'd ever consider joining herself, she added: "I think I'd be scared - dating's scary."
The former Spice Girls singer - who has five-year-old daughter Scarlet from her relationship with property developer Thomas Starr - has been linked to former 'X Factor' winner Matt Cardle and radio DJ Chris Moyles recently but insists she's not comfortable discussing her romantic life.
She added to Now magazine: "I'm not really talking about my personal life, I think it's safer kept that way. I've never been comfortable with having my personal life in the public domain."
However, Mel's fellow former Spice Girls singer Mel B isn't quite as reserved when it comes to speaking about her private life as she recently admitted she has experimented with women in the past.
When asked about straight women who had become lesbians, the 39-year-old singer said: "Yeah. I was one of those for a few years."

Naya Rivera thinks Mary J. Blige is "amazing" for banning her husband from having female friends.
The 'Glee' star, who wed Ryan Dorsey in Mexico in July just three months after ending her romance with Big Sean, doesn't trust other women around him and agrees with the 'No More Drama' hitmaker's marriage rules.
Discussing Mary's recent revelation that she and husband Kendu Isaacs agreed not to have pals of the opposite sex, the 27-year-old actress said: "I think that's amazing. I'm with Mary. I just got married and I'm pretty sure I told my husband that like two days ago."
Naya also told 'The View': "It's really not so much a rule as I understand it, because I feel like you're playing with fire and opening up the floodgates here, and you're having issues in your marriage, but someone is going to talk to the opposite sex to get advice or whatever and you should be talking to your partner. So I don't believe in it."
The brunette beauty insists she trusts Ryan but doesn't trust other women.
She said: "It's not so much that you like don't trust your relationship or your husband or your wife or anything. You kind of don't trust outsiders and other people. You don't know what their motives are.
"I feel like there's a difference between having an issue with that when you're married and when you're just dating someone. I feel like when you're married, if you're now someone's wife, I'm sorry, ladies, but you got to get back a little bit more. It's different."

Tracy Morgan is still "fighting to get better" following his car crash in New Jersey in June.
The former '30 Rock' star, who suffered brain injuries, a broken femur, broken nose and broken ribs when a Walmart truck smashed into the limo bus in which he was travelling in with friends in New Jersey, is trying to get back to the person he once was.
Speaking outside the federal courthouse in Trenton, New Jersey, his lawyer Benedict Morelli said: "Mr. Morgan is a fighter. He's fighting to get better.
"If there's a chance to be back to the Tracy Morgan he once was, he is going to try to do that. We just don't know."
But Morelli admitted Tracy is still struggling, according to NJ.com.
Asked if he is doing much better, he replied: "He's doing better.
"We are hoping and praying to get him back to the way he was. But the jury's out."
Tracy was extremely upset when Walmart recently accused him of being at least partially responsible for his injuries, as the company believes he wasn't wearing a seatbelt when the crash took place.
He hit back at the retail giant on Twitter, writing: "My friends and I were doing nothing wrong."
Aside from his physical injuries, Tracy is also grieving the loss of his friend James 'Jimmy Mack' McNair, 62, who was killed in the crash.

Nicki Minaj plans to take a "vacation" from music to have a baby.
The 31-year-old singer, who is gearing up to release her third album, 'The Pinkprint,' next month, says she would be "disappointed" if she isn't married with children by the time she releases her fifth album, but is worried she won't let herself take a break.
Asked what her biggest fear is, she said: "That I'll become so consumed with work that I'll forget to live my personal life to the fullest. If I'm done with my fifth album and I don't have a child by then, no matter how much money I have, I would be disappointed, as a woman, because I feel like I was put here to be a mother."
The 'Pills N Potions' hitmaker, who split from long-term boyfriend Safaree Samuels earlier this year, admits she has "put off" getting married in the past.
She said: "I have definitely put off the wife thing because I don't want people in my business. I'd rather not do anything that's going to be on paper but I definitely will be married before I have my baby. I want to make sure I do it in that order. I've always felt like that since I was young; my mother always put that in my head. By the fifth album, I will have walked down the aisle and I will at least be on baby number one, possibly baby number two. And have $500 million."
Nicki grew up in New York, but now lives in Los Angeles and feels guilty about not having enough time to spend with her loved ones.
She told Complex magazine: "I've struggled with a lot of guilt. When you're working and you're busy and you're successful, no matter what, something suffers, whether it's your relationship with your mother, your relationship with your whole family, not being able to go to your brother's graduation....
"I go to New York all the time and I'm so ashamed to say that I could be out there for a few days and not even be able to see my family because of my schedule."
