Tampa Bay Lightning forward Ryan Callahan will miss the 2016 World Cup of Hockey after having hip surgery on Tuesday.
Callahan, 31, had the operation to repair a labral tear in his right hip and is expected to miss five months, meaning he also could miss the beginning of the regular season.
The Lightning open the 2016-17 season at home against the Detroit Red Wings on Oct. 13
Callahan was selected in May to play for Team USA at the tournament which will take place at Air Canada Center in Toronto from Sept. 17-Oct. 1.
Callahan had 10 goals and 28 points in 73 regular-season games this season and two goals and four points in 16 Stanley Cup Playoff games.
