The New York Knicks confirmed on Saturday that Rasheed Wallace has a stress reaction and chronic condition in his left foot. The Knicks are still listing him as day to day, when he was previously diagnosed with a "sore left foot." Wallace, who had been serving as Tyson Chandler's backup at center, has missed the past four games, during which the Knicks have gone 2-2. With Wallace out, Chandler has been playing additional minutes. Not only is Wallace out, but Marcus Camby has plantar fasciitis.
