Cooke, whose blindside hit sidelined Boston's Marc Savard indefinitely with a Grade 2 concussion in Pittsburgh on March 7, took the ice for the first time 1:53 into the game as fans booed loudly. Just 5 seconds later, he and Shawn Thornton brushed against each other in the faceoff circle to the left of the Penguins net.
They dropped their gloves and, in a brief exchange, traded punches before Cooke's helmet fell off and he went to the ice. Thornton, who kept swinging while Cooke was crouched in a vulnerable position, was given a 10-minute misconduct.
