Senior hockey leagues are filled with guys that either have played at a higher level at one point or another and players that still have something to prove to themselves. Sometimes, a combination of those things leads to a pretty good fight, but when neither player shows any defence, things can get rather gruesome.
It seems like the next morning when one of the players showed off his injuries which include a bruised and bloody eye that's swollen shut, the other eye looks like it has some popped blood vessels and a cut above his eyebrow.
