Neither Shaw nor Calvert are feared fighters, and neither is over six feet tall, but in this even matchup they both showed their skills -- Shaw showing some savvy by actually taking Calvert's helmet off during the fight. Punching an unprotected face is a lot more fun than punching a visor, after all.
Following the fight, some fans were wondering on Twitter why Calvert didn't get an extra penalty for fighting with a visor. That penalty only applies if a player wearing a visor instigates a fight, which Calvert didn't do here.
