Shane Prince, who left Tuesday's game with an upper-body injury, and Calvin de Haan, who has been out with an upper-body injury since Dec. 16, did not skate.
The Islanders play the Boston Bruins on Thursday at Barclays Center then head out on a three-game road trip to Chicago, Arizona and Vegas before the all-star break.
UPDATE 1/18/18:
Casey Cizikas skated with the Islanders at Thursday's morning skate and stayed on for extra work after the optional team skate.
"Not ready, but skating well," Weight said. "Those upper-body injuries, we'll take them over the lower anytime. He can get out there and keep his wind up, but he's not ready yet. As desperate as things are, you have to push it but you have to make sure he's gonna be healthy when he plays."
Johnny Boychuk and Andrew Ladd both took the ice before the optional morning skate, with Boychuk briefly staying on, though he did not participate in any team drills. Weight did not have an update on either player.
