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

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.

Campbell has a 2-0-0 record with a 2.00 goals-against average and .923 save percentage this season.

Michael Hutchinson has been penciled in to back up starter Frederik Andersen for Toronto, which was set to finish a two-game series with Calgary on Tuesday night.

The Maple Leafs lost goaltender Aaron Dell to the waiver wire last week.
