Marie-Philip Poulin out vs. USA after blocking shot

Canada captain Marie-Philip Poulin will miss Thursday's pivotal clash against the United States at the women's world championship, director Gina Kingsbury said, according to Donna Spencer of The Canadian Press.

Poulin left Wednesday's game versus Switzerland in the third period after blocking a shot up high. Kingsbury said the star forward will be "resting for the next couple days."

The 30-year-old has notched one goal and two assists over three games so far during the tournament.

Thursday's contest between the North American juggernauts will determine the top spot in Group A. Both Canada and the USA have cruised to 3-0 records during the round-robin stage.
