The rock band’s lead singer suffered a nasty fall just two songs into a show in Gothenburg, Sweden on Friday (13 June) when he plunged off the stage.
Fans were left in shock as Dave led on the floor in agony for several minutes, before being taken backstage.
He told them: “Hey, ladies and gentlemen. I love you, but I think I just broke my leg. I really broke leg.
“I'm going to go to the hospital, I'm going to fix my leg, but then I'm going to come back.”
As the Dave then asked the rest of the band to carry on performing, he was taken to hospital where X-rays proved that he had indeed broken his leg.

But true to his word, he returned to the stadium with his leg wrapped up to finish the gig sat on a chair.
“I may not be able to walk or run but I can still play guitar and scream,” he told the crowd.
He later shared a picture of his X-ray on the band’s Twitter account, writing: "Thank you Gothenburg. That was amazing."
Dave’s ordeal drew some unlikely sympathy from Jedward’s Edward Grimes, who suffered a similar fate on stage at T4 On The Beach in 2010.
Dave Grohl is a hero for continuing on after breaking his leg! Feel so close to him right now because the same thing happened to me - Edward— JEDWARD (@planetjedward) June 12, 2015
Foo Fighters are due to headline Glastonbury later this month, with some fans speculating whether Dave will be forced to perform from the confines of a chair there too.
