Barzal, who missed 21 days earlier this season with an upper body injury, was hurt in the third period of the Islanders' overtime win at Tampa Bay on Saturday.

Anthony Duclair is the internal option and is being given a chance on the top line with Bo Horvat and Anders Lee. However, as long as he's still battling his lower-body injury, he's not able to be as effective.

New York Islanders forward Mathew Barzal is out indefinitely with a lower-body injury, the team announced Monday. Barzal, 27, played Saturday in a 3-2 overtime win over Tampa Bay but left late in regulation after blocking a shot.
