Good fight. Heard victory. AllMuscle (below) is very wrong; Trocheck definitely did not fall because of the refs, he fell because Heard KO'd him with that right uppercut that spun him around (then connected two more solid punches on Trocheck's way down).
Heard jumped Trocheck after backing down to Trocheck's initial request to fight. Trocheck was able to regroup and connect with multiple punches. Once the officials tried to seperate the two players, Trocheck was pulled back losing his footing and taking both players down to the ice. Fight over.
