New York Islanders goaltender Rick DiPietro is out indefinitely with a concussion.
DiPietro took a puck of his mask in practice Wednesday and did not play in Thursday's 5-1 win vs. Tampa Bay. He has yet to play this season.
Over the last three-plus seasons, DiPietro has played just 39 games due to a series of injuries. In 2007, he suffered a pair of concussions. He also has had surgery to repair a torn labrum in his hip and a series of procedures on his left knee.
In Sept. 2006, the Islanders signed DiPietro to a 15-year, $67 million contract. It is the longest deal since the new collective bargaining agreement was put in place in 2005.
The Islanders are off to a 2-1 start backstopped by goaltender Al Montoya, who has allowed four goals.
