Their biggest need is a point guard, but the struggling Knicks could really use all the help they can get, and losing a solid rookie big man off the bench won’t help much at all. After last night’s game against the Nuggets, ESPNNewYorkreported that Josh Harrellson will miss six weeks with a fractured wrist: “The Knicks have announced that Josh Harrellson has a fractured right wrist and will be out approximately six weeks after the time of surgery, which is not determined yet. Harrellson suffered the injury when he fell to the ground at the end of the first overtime in the Knicks’ 119-114 double-overtime loss to the Nuggets. Harrellson, who finished with only two points in 17 minutes, did not speak to reporters following the game.”
