Duclair (leg) is dealing with a long-term injury, Andrew Gross of Newsday reports Monday.

Duclair requires more testing to determine an exact timetable for his return. The Islanders expect to know more about the 29-year-old forward's status Tuesday. Duclair had two goals, one assist, eight shots on net and two hits in five outings before getting injured in Saturday's 4-3 shootout win over Montreal. Anders Lee may replace Duclair on the top line, while Simon Holmstrom could receive additional power-play time.
