Blackhawks forward Patrick Sharp is expected to miss most of training camp and the preseason after undergoing an emergency appendectomy Monday night.
"Sharp underwent an emergent surgical appendectomy [Monday] evening after experiencing some abnormal abdominal discomfort," head team physician Michael Terry said. "The surgery was successful and I anticipate a full recovery in approximately three to four weeks."
Training camp starts Friday with media day at the United Center. The first on-ice sessions are Saturday. It's possible that Sharp could miss the season opener against the Dallas Stars Oct. 7 if he needs four weeks to recover from the surgery.
Sharp signed a five-year extension worth $29.5 million in August after an All-Star season. He led the Hawks with 34 goals. Sharp missed seven games last year with a left knee injury.
Winger Patrick Kane is still expected to participate in training camp after undergoing wrist surgery to repair a fracture earlier this summer.
