DAVE GROHL BREAKS A LEG DURING CONCERT … Watch Video

Dave Grohl tried to be the toughest man in Sweden … after falling off stage, breaking his leg — and attempting to keep the concert going.

According to Swedish witnesses (thanks Google translate) … it seems the Foo Fighters frontman jumped down from the stage early on during the band’s concert Friday night, and sustained a pretty serious injury.

Still, Dave kept on singing, ironically … “Under Pressure.” But once the song was over … Grohl had to wave the white flag, and announced they were gonna have to cut the show short since he needed medical attention. Dave says he thinks the leg is broken.

As one fan put it, “Det kallar jag en riktig rockstjärna!”

Exactly.
