Montreal Canadiens defenseman Kaiden Guhle will be out indefinitely after undergoing surgery to repair a lacerated quadricep muscle, the team announced on Wednesday.

There’s no sugar-coating the Kaiden Guhle injury for the Montreal Canadiens. It’s a huge blow to a team that, with exception to fourth-liner Emil Heineman, had finally been healthy with the recents results to by and large match.

The Montreal Canadiens may be without one of their top defensemen after Kaiden Guhle suffered an undisclosed lower-body injury in Tuesday’s 4–1 loss to the Winnipeg Jets.
