Below is an excerpt from the TSN post practice article:

He has not been cleared to play yet, but Montreal Canadiens forward Andrei Kostitsyn practiced Monday in his usual spot with Tomas Plekanec and Alex Kovalev. It’s the second time he has skated since being concussed two weeks ago, and the team is hopeful he will return to action soon.

Kostitsyn is awaiting medical confirmation to decide whether he will face the Carolina Hurricanes Tuesday or miss his third game. The decision could come later today.
