Eddie Lack made 27 saves in relief of an injured Ryan Miller and the Vancouver Canucks beat the New York Islanders 4-0 on Sunday.
Zack Kassian, Radim Vrbata and Bo Horvat scored in the second period for Vancouver, which kept pace in the tight Western Conference playoff race.
The 34-year-old Miller, in his first season with the Canucks, left with an apparent leg injury early in the second after he was run into by teammate Jannik Hansen in the crease. Miller stayed down and was in pain after the collision and appeared to flex his right leg as he left the ice.
Lack replaced him at 1:11 of the middle period after Miller made 10 saves.
The Islanders lost their second straight this weekend following a 3-2 shootout loss at Washington on Saturday.
They still lead the Metropolitan Division with 80 points and are 21-8-0 at Nassau Coliseum this season. They have three more games this week against Arizona, Calgary and Carolina.
New York had been shut out only one other time this season, a 5-0 loss at Colorado on Oct. 30.
