CALGARY, Alberta -- Toronto Maple Leafs backup goaltender Jack Campbell will be out "weeks" with a leg injury, according to head coach Sheldon Keefe.

Campbell was hurt late in Toronto's 3-2 win at Calgary on Sunday when Flames forward Matthew Tkachuk landed on him in a goalmouth scrum.

The Columbus Blue Jackets have placed center Brandon Dubinsky on Long-Term Injured Reserve, club General Manager and Alternate Governor Jarmo Kekalainen announced today.

Dubinsky, 34, has not appeared in a game since the 2019 Stanley Cup Playoffs, missing all of the 2019-20 campaign due to a chronic wrist injury.  

The Jets placed forwards Patrik Laine and Nate Thompson on injured reserve Friday.

Laine has missed the past three games with an upper-body injury. He had two goals and an assist in the Jets' season opener before being sidelined.

Thompson suffered a lower-body injury Thursday in a win over the Ottawa Senators. He has been held pointless through four games.

Maple Leafs forward Joe Thornton will miss at least four weeks because of a fractured rib.

After being injured during Wednesday's 3-1 loss to the Edmonton Oilers, Thornton has been placed on long-term injured reserve, a move that helps the team's salary-cap situation.

The Chicago Blackhawks have placed captain Jonathan Toews and young center Kirby Dach on long-term injured reserve.

The move means that each player must miss at least 10 games and 24 days. The Blackhawks also gain some financial flexibility to go over the salary cap while the players are out.

Buffalo Sabres center Zemgus Girgensons is expected to miss the regular season after undergoing surgery for a hamstring injury, the team announced Wednesday.

Girgensons suffered the injury during a scrimmage Monday.
