The Maple Leafs could seek depth at forward before the deadline after Andreas Johnsson sustained a knee injury on Thursday that will keep him out eight weeks.
Maple Leafs coach Sheldon Keefe said the forward, who was injured in the first period of a 3-2 loss to the Dallas Stars, would need surgery. Johnsson has 21 points (eight goals, 13 assists) in 43 game this season.
Toronto is also without forward Ilya Mikheyev because of a wrist injury.
Keefe also said defenseman Morgan Rielly, who fractured his foot on Jan. 12, likley would not be back until the end of March.
General manager Kyle Dubas told NHL.com on Feb. 6 Rielly's status could determine what the Maple Leafs do ahead ahead of the deadline. Now, they have the Johnsson injury to contend with as well.
The Maple Leafs (30-20-8), who visit the Ottawa Senators on Saturday (7 p.m. ET; CBC, SNO, SNW, SNP, NHL.TV), are in third place in the Atlantic Division, 13 points behind the Tampa Bay Lightning and two points ahead of the Florida Panthers.
