It's no wonder Katt Williams got tossed around like a rag doll by a 17-year-old boy ... the kid was a bona fide high school wrestler.
Luke Wash, who wrestled for Gainesville High, is no stranger to the choke hold in which Williams found himself. Take a look at the pic -- it's easy to see, Luke's a natural as he towers over his opponent.
As TMZ reported ... Luke and Katt got into it during a soccer game, and the jawing continued after the match. Luke got in Katt's face, Katt punched him and Luke took the comedian down.
We're told cops are investigating the incident and the consequences could be serious for Katt ... his bail could be revoked.
