Shaw will not suit up for Friday night's game against the Sharks due to concussion-like symptoms he developed Thursday afternoon. Additionally, he will not travel with the team to Washington, essentially ruling him out for Saturday's showdown with the Capitals.
EDGE Analysis
While the Canadiens haven't officially diagnosed Shaw with a concussion, they are clearly concerned enough with the symptoms he was displaying to sit him for at least the next game or two. The Canadiens haven't played since Monday when they lost to the Bruins in overtime, so it's unclear when exactly this injury occurred. Assuming he does not make the trip to Washington on Saturday, Shaw could be back in the lineup for Tuesday's home game against the Ducks, though that really depends on if he can pass the league's concussion protocol before then.
