Travis Scott made a pretty nasty fall while opening up for Rihanna's ANTI tour in Philadelphia last night.

Scott is known for getting rowdy -- his last album was called Rodeo after all. But the 23-year-old rapper got carried away and took a stumble as he performed one of his hit singles, "Antidote."

Afterwards, the stunned rhymer grimaced in agony as he placed a hand on his head. But it wasn't long before he was back on stage to perform the rest of the track. What a trooper.

Check out the clip above.
