SOCHI, Russia - Team Canada cannot replace the injured John Tavares on the roster for the rest of the Olympics, but Matt Duchene is available to step into the lineup.
Duchene, who was scratched for the opener against Norway and then Wednesday night's quarter-final against Latvia, is expected to step into Tavares' spot on the fourth line when Canada plays the United States on Friday for a spot in the gold-medal game.
Duchene took line rushes between Patrick Sharp and Rick Nash at practice Thursday as the rest of Canada's lines remained the same.
Tavares suffered a left-leg injury in Canada's 2-1 win over Latvia and coach Mike Babcock said the New York Islanders star is out for the rest of the tournament.
That's a major loss for Canada, even though Tavares did not record a point in three-plus games.
It will be up to Duchene to provide the same stability in the middle of the fourth line and perhaps even add a scoring spark to a lineup that needs it. Canada has scored just 13 goals in four games, and only six have come from the forwards.
