KO Basketball

A sport that you don't see on TV, though it would be interesting.

That guy just got his glasses shattered by the basketball and the ref didn't call a foul even though he's got blood in his eyes. He's going to be in trouble if it gets much worse, why doesn't he just play regular basketball instead of KO basketball? Why does he keep doing this to himself?
