Canada goes head to head with the United States in the marquee match-up at the women’s hockey tournament on Tuesday. It will do so without the help of team captain Marie-Philip Poulin.

Poulin, a four-time Olympic medalist, (three gold, one silver), suffered an apparent injury to her right leg after taking a body check in the first period of Canada’s win over Czechia Monday. She was ruled out for Tuesday’s game against the United States on Tuesday afternoon, Canadian Olympic Committee said in a statement.

In the U.S. (2-0), Canada is going up against the gold-medal favourite. Though the Canadians have taken gold at this tournament in three of the last four Winter Games, they are the clear underdog against the Americans this time around.
