Habs defender Sami Niku out indefinitely with concussion

Montreal Canadiens Defender Sami Niku has suffered a concussion and will be sidelined indefinitely.

Head coach Dominique Ducharme announced the news on Saturday morning.

Niku fell in action in the first period of a preseason game between the Canadiens and the Ottawa Senators on Friday after he was hit from behind by Forward Josh Norris. Norris won't face consequences for the move. 

After having difficulty returning to the bench, Niku headed to the locker room with the support of a sports therapist.

It was Niku's first pre-camp outing, a week after signing a one-season contract with the Canadiens as a free agent.
