Stoudemire had been playing well for the Knicks before his injury. Smith had 19 points in the Knicks' win over Cleveland on Thursday starting for Shumpert. Knicks guard Iman Shumpert will miss his second straight game due to a left shoulder sprain, but New York will get Kenyon Martin and Amar'e Stoudemire back from their respective ankle injuries for Saturday night's game against Miami. J.R. Martin has missed six of the last seven games due to a left ankle injury and Stoudemire has missed the last seven with an ankle sprain. Shumpert originally hurt his shoulder on Tuesday against Boston in a collision with Kris Humphries. Martin has provided strong defense on the interior for New York , winners of four straight heading into Saturday's game against the Heat. The power forward averaged 13.2 points on 56 percent shooting in 23 minutes over his past 12 games.
