Casey Cizikas has been placed on injured reserved retroactive to Feb. 21, the Islanders announced Thursday.
He will miss four weeks due to an upper-body injury, Arthur Staple of Newsday reported Wednesday.
Cizikas suffered the injury during Tuesday night's win over the Red Wings.
The Isles have yet to announce who will be replacing Cizikas on the roster.
The 25-year-old has seven goals and 16 assists in 53 games for the Islanders this season.

Bad news on the injury front as Cizikas is now lost for the next month with the team only one game into their brutal nine-game road trip.
Obviously suffering from a broken hand/finger courtesy of a wicked slash last night, the X-ray machine was not kind to the Islanders today. The word on Cal Clutterbuck is he will try to push through his lower body injury and skate tomorrow morning before the team takes on the Montreal Canadiens.
With Shane Prince moving to IR today, retroactive to Feb. 12, he can be activated at any time, meaning the Islanders could just swap him for Cizikas on said list and keep Bracken Kearns around as fourth-line filler once the former is healthy enough to play, which seems to be not far off.
It makes Garth Snow's performance over the next week leading to the trade deadline that much more important now, as New York is within striking distance of a playoff spot and need to continue capturing points on the road. Can he, with Jonathan Ledecky's backing, go out and hook the big fish? He almost has to.
