I'm not surprised they prosecuted a player for attacking a teammate. A buddy of mine got put on probation for hitting a guy during a bench-clearing brawl during a men's rec league game years ago, and the other guy also got probation for slugging my buddy. Since the cops could not determine who started the fight, and who hit who first, the arrested my buddy and the other player because they both had admitted to hitting each other and left physical evidence on each other.
