It’s customary to wish performers good luck by saying "break a leg" before they take the stage. However, Dave Grohl might have taken that sentiment a little too literally at a concert in Sweden on Friday.

The Foo Fighters frontman reportedly took an ill-advised stage dive during the band's second song and came up lame, though, in true rock star fashion, he finished out the song before admitting defeat.

"I think I just broke my leg," Grohl can be heard telling the audience in video taken after his fall. "I think I really broke my leg. So look, you have my promise, right now, that the Foo Fighters, we gonna come back and finish our show. But right now...I’m gonna go to the hospital and I’m gonna fix my leg. But then I’m gonna come back and we’re gonna play for you again!"

The crowd was silent as Grohl made the announcement, repeating "I’m so sorry" several times as emergency personnel carried him off-stage. However, the performer kept his word, returning to finish out the band’s set, while seated with his leg in a cast.

Fans took to social media to sing the rocker’s praises, dubbing him everything from a "lad" to a "LEG-END" for powering through the injury.

Grohl later tweeted a picture of his X-ray from the Foo Fighters account, writing "Thank you Gothenburg. That was amazing."
