NLE Choppa is having trouble staying on his feet.

Earlier this week, Chris Brown crossed Choppa to the ground during a celebrity basketball match.

Now there's a video of a man approaching NLE at the airport, asking him his name, and then attacking him when he confirms who it is.

The word on the Internet streets is the man was an NBA YoungBoy fan, peeved that NLE and NBA have been beefing.

Choppa denies he got knocked out and says he slipped and then chased the guy off.  This video angle suggests it may be slippage, but it also may not be the whole story.
