The surgery was performed at UPMC Presbyterian Hospital by team physician, Dr. Dharmesh Vyas, and Dr. Ivan Tarkin of UPMC Orthopaedic Trauma Surgery. Guentzel is expected to miss four to six months.

Guentzel, 25, injured his right shoulder when he fell awkwardly into the boards while scoring his 20th goal of the season during the third period of the game last night against the Ottawa Senators. The NHL All-Star leads the team in goals (20) and points (43).
