Injured Bruins defenseman Adam McQuaid participated in the team's optional skate Saturday morning but his status remains questionable as the Bruins prepare to host the Sharks. "I'm just waiting for more information before I can even make any decision on him," said Bruins coach Claude Julien. "He skated again this morning so he's really coming around." McQuaid has missed the last three games after slamming head first into the boards during a game in Carolina on Oct. 12.
