UPDATE:JR Smith confirmed the signing on Twitter this morning: “New York Knicks It Is!”

The immortal JR Smith, as expected, will soon be wearing a New York Knicks uniform. According to the NY Post, Smith will be at MSG for tonight’s game as a spectator: “The Knicks will officially add free agent reserve shooting guard J.R. Smith to Linsanity today, making the hottest team in the NBA a deep team as well. According to multiple sources, Smith, who played in China during the lockout and became eligible to sign an NBA deal on Wednesday, will be at the Garden tonight, but won’t make his debut until Sunday against the Mavericks. The Knicks have to cut a player to make room for Smith and Renaldo Balkman, who has been out of the rotation since early January, is the expected candidate, according to a source. Coach Mike D’Antoni was never a big fan of Balkman, a throw-in to the trade with the Nuggets for Carmelo Anthony. Balkman has one remaining year at $1.8 million and could have been an amnesty casualty if the Knicks were still going for 2012 cap space.”
