The banged-up St. Louis Blues got more bad injury news Tuesday with word that defenseman Carl Gunnarsson won't play again this season and forward Ivan Barbashev is out at least six weeks.

Gunnarsson injured his right knee when he got tangled up with Kings forward Gabe Vilardi midway through a 3-0 loss to Los Angeles on Monday night. Barbashev had surgery on his left ankle Tuesday morning and will be reevaluated in early April.

Buffalo Sabres defenseman Jake McCabe will miss the rest of the season after he injured his right knee during Saturday's 3-2 victory at New Jersey.

The 27-year-old McCabe was diagnosed Monday with ligament and meniscus damage, and the team said he will need six to eight months to recover.

The struggling New York Rangers will be without defenseman Jacob Trouba for the next four to six weeks because of a broken thumb.

That's a significant blow to an underachieving team with playoff aspirations that has lost four in a row.

"Unfortunately, we're going to miss everything he brings from a physicality standpoint, from a compete standpoint, from what he brings to us from a leadership standpoint," coach David Quinn said Wednesday

The Maple Leafs will be without Wayne Simmonds until mid-March.

The team announced Monday that the bruising winger is set to miss six weeks after suffering a broken wrist in Saturday's 5-1 victory over the Vancouver Canucks.

The Blue Jackets placed goaltender Elvis Merzlikins on injured reserve after he was injured during practice.

Carolina Hurricanes goaltender Petr Mrazek is out indefinitely after having surgery on his right thumb, general manager Don Waddell said Wednesday.

Mrazek is 2-1, with both wins coming via shutout, and he leads the NHL with a 0.99 goals-against average and a .955 save percentage this season.

Colorado Avalanche star center Nathan MacKinnon has a lower-body injury that will sideline him "week-to-week," coach Jared Bednar said Tuesday.

MacKinnon suffered the injury in Sunday's loss to the Wild and missed Colorado's victory Tuesday over Minnesota. Bednar did disclose any specifics about the injury.
