The two enforcers engaged with one another as Orr and Carter Ashton were trying to score on a two-on-one break early in the third period. As referees were approaching to stop the bout, Parros fell to the ground and drove his shoulder and head into the Bell Centre ice.
Although Orr was pulling his jersey as he was falling, Pierre LeBrun of ESPN points out that Parros' injury appeared to be self-sustained.
Lying on the ground motionless, the 33-year-old winger was quickly attended to by the trainers on-hand. He was then taken off the ice on a stretcher, with his head and neck put in protective restraining devices.
In the aftermath of the brawl, both men were awarded game misconducts. Orr was awarded 29 penalty minutes in his only shift on the ice.
Tuesday's ugly development is just the latest in a long rivalry between two of the game's fiercest enforcers. Parros and Orr have a long history of fighting dating back to Parros' days with the Anaheim Ducks, often engaging one another from the first moment they share the ice.
Parros was playing in his first game with Montreal after coming over from the Florida Panthers this summer. Orr, 31, is in his fifth season in Toronto.
