"That play should have been penalized," the NHL commissioner told Canadian lawmakers while testifying before a subcommittee on sports-related concussions on Parliament Hill in Ottawa on Wednesday, according to TSN's Rick Westhead. "Sometimes things are missed on the ice. Our officials must have the most difficult job in sports."
Bettman told the panel that the NHL Department of Player Safety has warned Marchand about his behavior and that if it's repeated, "he should look forward to a suspension."
Last May, the NHL said it warned the talented Bruins pest that "similar behavior in the future will be dealt with by way of supplemental discipline" after he licked the face of then-Toronto Maple Leafs forward Leo Komarov.
At Wednesday's testimony, Bettman once again refused to acknowledge a link between repeated brain trauma and CTE, a brain condition associated with repeated blows to the head.
The commissioner also said banning all hits to the head wouldn't be feasible if the NHL "is to be maintained as a physical contact sport."
