He broke his leg in a horrific fall from the stage during a gig in Gothenberg, Sweden on Friday.

But on Sunday Foo Fighters singer Dave Grohl did his best to put a brave face on the situation, as fans anxiously await news on the band's upcoming London gigs.

The rocker was spotted out in London, resting up in a wheelchair as he headed out into the city with wife Jordyn and their daughters.

He's cheery! David Grohl flashed a big smile and gave a thumbs up as he used a wheelchair in London on Sunday, two days after breaking his leg during a gig in Sweden

The musician was dressed down, teaming a hooded sweatshirt with shorts, meaning his huge cast was clearly on show.

Joined by Jordyn, who he married in 2003 and their three daughters, Violet Maye, nine, Harper Willow, six, and Ophelia Saint, who was born last August, Dave seemed to be in some pain as he was wheeled along but later gave a big thumbs up.

Grohl tumbled during the second song of the Foo Fighters Sweden show and badly injured himself. While he waited for medical attention he told the audience: 'Hey, ladies and gentlemen, I love you too motherf******. Now look I think I just broke my leg. I think I really broke leg.'

He added: 'So look, you have my promise, right now, that the Foo Fighters, we're gonna come back and finish the show. Ladies and gentlemen, right now I'm gonna go to the hospital. I'm gonna fix my leg.'

A recumbent Grohl at first jokingly sang the David Bowie and Queen song Under Pressure, before going off for treatment.

As the audience clapped and whistled he added: 'But then I am going to come back, and we are gonna play for you again. I'm so sorry. I'm so sorry. We are gonna do it.' Speaking to drummer Taylor Hawkins he asked him to carry on saying: 'You gotta do it.'

While he was being seen to by medical professionals, the rest of the band played covers which were sung by Hawkins.

He's back! Dave was spotted out and about on crutches in London later on Sunday

After having his leg bandaged, Dave returned to the stage and finished the concert sitting in a chair. He told the audience: 'I may not be able to walk or run but I can still play guitar and scream.'

He completed the set alternately performing with crutches or sitting on a chair, according to footage shared by fans, immediately propelling him into music folklore.

Fans have been left worried that the Foo Fighters Wembley Stadium gigs this weekend and their headline slot at Glastonbury next Friday will be cancelled as a result of Grohl's injury.

The band have already announced it was cancelling its next two concerts - an appearance at Pinkpop festival in the Netherlands on Monday and a show at the AFG Arena in Switzerland on Tuesday, but there's been no word yet on the London gigs on Friday and Saturday.

The fact that Grohl has jetted to the capital though is a good sign he's determined to play for his UK fans.

'As witnessed by tens of thousands in attendance at Foo Fighters' June 12 show at Ullevi Stadium, Dave Grohl took a nasty spill during the second song of the set,' the band said in a statement posted on Twitter over the weekend.

'With the help of on-site medical staff who patched him up temporarily, Dave was able to rejoin the band to complete that performance.

'While the full extent of Dave's injuries are still being determined, it was confirmed at a post-show hospital visit that he sustained at least one fracture.

'As a result Foo Fighters have been forced to cancel their June 14 appearance at the Pinkpop Festival as well as their June 16 show at the AFG Arena in St. Gallen, Switzerland.'

A statement on the Wembley Stadium website posted on Saturday adds: 'We are aware of the incident last night involving Dave Grohl and are in contact with the event organisers, who at this stage have no further information. As soon as we have news from the artiste this will be made public.'

Dave is not the first musician to break an bone and soldier on for the sake of the audience.

At the Coachella Music festival in April Florence Welch broke her foot when she jumped off stage.

The Florence And The Machine front woman sat on a chair for the rest of the performance.

Meanwhile Enrique Inglesias fell victim to a drone when he caught it in his hand at his Tijuana concert in May.

It is trick he had done before but this time it went awry.

The singer was left with a bloodied hand but carried on performing.
