Minnesota Wild forward Matt Cooke is facing a lengthy suspension in these Stanley Cup playoffs for an ugly knee-on-knee collision that injured Colorado Avalanche defenseman Tyson Barrie on Monday.

The NHL’s Department of Player Safety has offered Cooke an in-person hearing, which means a ban could exceed five games. A date and time was not announced. The department made the announcement via Twitter.

It was reported following Monday’s game that Barrie suffered an MCL injury and is out now four-to-six weeks.

The incident took place early in the second period of the Wild’s 1-0 overtime victory over the Avalanche. Colorado still leads the series 2-1.
