Second year forward Renaldo Balkman will miss at least the next four weeks with a stress reaction and cartilage injury to his right ankle.  Balkman played in 68 games as a rookie and he averaged 4.9 points, 4.3 rebounds and 0.6 assists per game off the bench.  Balkman was going to be nothing more than a reserve this season so the Knicks probably won’t miss him that much while he is out.
