Petry walked away from the rink to undergo treatment, the Montreal organization said.

Petry had two assists in the Habs ’8-4 loss to the Washington Capitals on Saturday night while posting a respectable 20:33 playing time.

Kale Clague replaced Petry with veteran Joel Edmundson.

All other players participated in training, including goaltender Carey Price.

Forward Rem Pitlick suffered a bad fall on the rails during the drill mid -session and looks shaky. However, he got up and, after regaining his sanity, resumed his place in the ranks.

The Canadiens will host the Minnesota Wild and their goaltender Marc-André Fleury at the Bell Center on Tuesday night. He will try to end the series with five defeats, he who has compiled a 2-8-1 record in his last 11 confrontations.

It is not yet known which goaltender interim head coach Martin St-Louis will be sent to the mess for the occasion.
