Canucks winger Alex Burrows left Canada's opening game with Slovakia at the World Hockey Championships in Helsinki, Finland on Friday with an apparent head injury.

There is obvious concern he suffered a concussion when he fell awkwardly in the second period of the game — which Canada won 3-2 — in a collision with two Slovak players. He appeared to hit his head on the ice after falling awkwardly and appeared woozy as he left the ice. Burrows didn't return to the game.

Hockey Canada spokesman Andre Brin said in an e-mail to The Province that Burrows was "day-to-day" with an "upper-body" injury. Brin said Burrows will be re-evaluated tomorrow, but is doubtful for Canada's matchup with the U.S. (8:45 a.m., TSN). Canada's next game is Tuesday versus France.

TSN reported that Team Canada GM Kevin Lowe said the (injury location) is "real high." Lowe said Hockey Canada follows the same concussion protocol as the NHL. He also said Burrows was "fine" in the locker room.
