MILAN — Even when he couldn't be in the lineup because his right leg had buckled in ways legs shouldn't, Sidney Crosby made a difference for Canada.

With the quarterfinal against Czechia tied after two periods, Crosby addressed his teammates. The gist of the message? Go get 'em.

Canada did. Mitch Marner scored 1:22 into overtime to seal a 4-3 victory, sending Canada to the semifinals on Feb. 20 at Milano Santagiulia Ice Hockey Arena. Whether the lineup will include Crosby is unknown; Canada coach Jon Cooper did not have an update immediately after the game.

Crosby was hurt on a hit by Radko Gudas, and also absorbed a hit from Martin Necas in the second period.

"He couldn't come out for the third," Cooper said. "But he did address the players, and I think that was a big thing coming in is, that we lose this game − we didn't want this to be Sid's last game at this Olympics"
