Pittsburgh Penguins prospect Angelo Esposito will not compete in the eight-game Canada-Russia Super Series because of a groin injury.
Esposito, an 18-year-old native of Montreal, was expected to be one of Canada's top offensive threats at the junior hockey series.
Selected in the first round (20th overall) of this year's NHL draft, Esposito will not be replaced for the four-game Russian leg of the series, which begins Aug. 27 in Ufa, Russia.
Canada will proceed with a roster of 25 players, including three goaltenders, eight defencemen and 14 forwards.
Esposito scored 27 goals and collected 79 assistsin 60 games for the Quebec Remparts of the Quebec Major Junior Hockey League last season.
He also led the Remparts to the Memorial Cup championship in 2006.
The Canada-Russia Super Series will take place from Aug. 27 to Sept. 9.
The four games in Canada will be held in Winnipeg (Sept. 4), Saskatoon (Sept. 5), Red Deer, Alta., (Sept. 7) and Vancouver (Sept. 9).
