The Jets just tweeted the news:
#NHLJets forward, Evander Kane, has been moved to the injured reserved list, retroactive to Jan. 26.
Kane injured the hand in a Jets loss against the Lightning when he got into it with the Bolts Eric Brewer. He came back and played three games about two weeks later (vs. Ana, SJ and Tor) but Coach Maurice announced on January 28th prior to the Predators game that Kane would be out until after Olympic break.
