Goddamn that exactly shyt happened at my college.
One of our linebackers was playing in an intramural league. I wasn't there, but from what I understood happened, they were already getting beat and the game was pretty much over when the other team had a fast break. He recovered late and "intentionally fouled" him to send him to the line, but straight up knocked the guy so hard he hit the wall. He was a good guy and afaik never once had any problems with aggression or anything beyond being a linebacker, but a LOT of people thought he was taking out his anger at losing on the other team. The kid who got hit was shaken up real bad and some people on campus who didn't like the team wanted him to be suspended/expelled/charged or some shyt
