corkdork- I don't know what fight you watched, but Sully knocked down Olson and let him back up, and Olson fell at the end, and Sully stopped, because he is a classy fighter who knows the code. Go Gladiators!
Five seconds into the game, Olson and Sullivan dropped gloves. At first, it looked like a hug fest; each man had the other's jersey in their left hand, and they were circling at center ice. Eventually, though, blows began getting exchanged. For the first 4 or 5 shots, it was one-to-one, then Olson landed a series of hits to Sullivan's face, knocking Sullivan to his knees. Sullivan got up before the linesmen could step in, and they began anew. However, for this go-round, Olson definitely had the better of him, and Sullivan had to end the fight by shoving Olson down, whereupon the linesmen jumped in and escorted the two to the penalty box.
