Boston Bruins' forward Brad Marchand caused quite the stir in Game 3 of the Bruins' playoff series against the Columbus Blue Jackets. 

Marchand gave a bit of a punch to the back of Scott Harrington's head during a scrum in front of the net. 

Some fans and analysts screamed for Marchand to be suspended due to his history and label as a repeat offender. 

However the NHL announced on Wednesday that there wouldn't be any discipline laid on the forward. 

NHL Commissioner Gary Bettman spoke to the media on Wednesday and said that the play should have been penalized and Marchand has been warned that a repeat of the action will result in a suspension "he should look forward to a suspension."

"That play should have been penalized," Bettman told TSN's Rick Westhead. "Sometimes things are missed on the ice. Our officials must have the most difficult job in sports."

What do you think of Bettman's comments?
