Vince Neil Injured After Falling Offstage at Concert, Rushed to Hospital - TMZ

Vince Neil was on his game Friday night during a concert ...

He was a few songs into his set when he stepped to the edge of the stage, and then suddenly tumbled 4 feet onto the cement.

Turns out there was a small gap between the speaker and the stage that Vince didn't see and he fell through the crevice onto the floor.
