Utterly remarkable stuff from ESPN Boston's Joe McDonald:

Boston Bruins forward Gregory Campbell suffered a broken right leg and is done for the season, according to a team source.

Campbell suffered the injury when he blocked a slap shot by the Penguins' Evgeni Malkin during a Pittsburgh power play in the second period of Wednesday's 2-1 double-overtime victory in Game 3 of the Eastern Conference finals at TD Garden.

After blocking the shot, Campbell remained on the ice for more than a minute in obvious pain and helped the Bruins kill off the penalty.

"The guy had a [shooting] lane and he sacrificed his body and it was a great thing," Bruins goaltender Tuukka Rask said. "It's a bad thing he got hurt. He blocks a lot of shots and he took one for the team there, and we really wanted to win this for him."
