NHL commissioner Gary Bettman upheld the four-game suspension given to Boston Bruins defenseman Charlie McAvoy for an illegal check to the head of Florida Panthers defenseman Oliver Ekman-Larsson on Oct. 30.

Since the suspension is less than six games and did not involve an in-person hearing with the NHL Department of Player Safety, McAvoy is ineligible to appeal Bettman’s decision to a neutral arbitrator.

McAvoy’s appeal hearing was held Tuesday. The NHLPA asked for Bettman to reduce the suspension from four games to three.

In his ruling, Bettman noted that McAvoy had acknowledged that he did not deliver the check as he intended and that he had made a mistake because of “a split-second decision.” McAvoy also said he did not intend to injure Ekman-Larsson.
