CALGARY - The Calgary Flames say 18-year-old centre Sam Bennett needs shoulder surgery and will be out four to six months.
The Flames drafted Bennett fourth overall in this year's NHL draft, making him the highest selection in Calgary's history.
He was limited to three pre-season games and missed parts of main camp because of a groin injury coming out of rookie camp, which was followed by his shoulder troubles.
Bennett said he had shoulder troubles last year but kept quiet about the pain because he wanted to be in the Flames' lineup.
Bennett, a six-foot-one 180-pound forward from Holland Landing, Ont., had 36 goal, 55 assists and 118 penalty minutes in 57 games with the Ontario Hockey League's Kingston Frontenacs last season.
