NEW YORK -- Team Canada has added Ryan O'Reilly to its roster for the World Cup of Hockey to replace the injured Tyler Seguin.

Hockey Canada announced the decision Tuesday.

O'Reilly had 21 goals and 39 assists in 71 games last season, his first with the Buffalo Sabres. He won the Lady Byng Trophy for the 2013-14 season while with Colorado and has at least 50 points in four of the past five seasons.

Seguin, a forward with the Stars, played in Canada's first two pre-tournament games against Team USA, getting an assist in a 5-2 win Saturday. Hockey Canada did not specify Seguin's injury.

Canada plays its first World Cup game on Saturday against the Czech Republic.
