The Montreal Canadiens enforcer, who has already missed time this season with a concussion, was knocked down during a bout with Boulton but was visibly wobbly after the altercation.
He was originally sent to the penalty box, but then taken to the dressing room to assess his situation.
The Hockey Night in Canada panel discussed the situation during the After Forty segment, saying it was the right move by the referees to take Parros out of the game and suggesting it may be time for him to hang up the skates.
