Orangeville -Ont. — A knee injury has ended Dana Tyrell's world junior hockey tournament before it had even begun.

Hockey Canada announced Sunday that the Prince George Cougars forward would be unable to play in the world tournament in Ottawa after injuring his knee in Friday's 4-2 exhibition win over Sweden in Toronto.

The 19-year-old Tyrell, who's the Cougars' leading scorer and team captain, was skating on a line with John Tavares on Friday night. Tyrell didn't return to play in the third period however. The Airdrie, Alta., native was scheduled to return home Sunday.

Tyrell has played for Canada once, at the 2007 Canada-Russia Super Series. Last year, he suffered a knee strain that hampered him at the national junior team's final selection camp and he was released.

Tyrell will be lost to the Cougars for the remainder of the season.
