Jake Muzzin will be out at least three weeks for the Toronto Maple Leafs because of a lower-body injury.
The defenseman left a 3-2 overtime loss to the Montreal Canadiens in Game 6 of the Stanley Cup First Round on Saturday during the second period.
Toronto will host Montreal in Game 7 of the series Monday (7 p.m. ET; CNBC, CBC, SN, TVAS). The winner will play the Winnipeg Jets in the Stanley Cup Second Round.
Muzzin has scored three points (two goals, one assist) and is averaging 19:30 of ice time in six games in the Stanley Cup Playoffs. He leads Maple Leafs defensemen with 16 hits and his 11 blocked shots are second to Morgan Rielly (13).
Muzzin scored 27 points (four goals, 23 assists) and averaged 21:35 in ice time in 53 games in the regular season and led Toronto with 101 hits and 94 blocked shots.
Rasmus Sandin, who was scratched in Game 6, will replace Muzzin in the lineup. He has one goal in four playoff games.
