The Ottawa Senators knew Alex Burrows was facing a suspension, but 10 games caught them by surprise.

The NHL department of Player Safety handed Burrows a 10-game suspension Wednesday night for kneeing New Jersey's Taylor Hall during a game Tuesday.

"We disagree, but we respect the league's process and decision," said Senators coach Guy Boucher.

Hall caught Burrows with a hard check and Burrows replied by chasing down the Devils forward before punching and kneeing him in the helmet. He will forfeit $134,408.60 of his salary during his suspension.

"For the sole purpose of retribution, Burrows drags an unwilling opponent to the ice. Punches him several times, then uses his knee pad to violently inflict more punishment on his opponent's head. This is a dangerous and unjustifiable attack," said a statement from Player Safety.

Senators teammate Mark Stone called the suspension "a bit harsh."

"Obviously it's a suspendable play, but 10 games seems a bit harsh especially considering he doesn't really have as much of a history as people may think," Stone said

Burrows, despite being known for his borderline play, had only been suspended once before in his NHL career before Wednesday night. He picked up a three-game ban in October 2014 while with the Vancouver Canucks for an illegal check to the head of Alexei Emelin. The 36-year-old has also been fined twice in his career and dodged punishment for an alleged bite to the finger of Patrice Bergeron during the 2011 Stanley Cup Final.
