The New York Knicks practiced Monday without forward Kenyon Martin or guards J.R. Smith and Iman Shumpert.

Martin and Smith are ill and questionable for Tuesday night's game in Indianapolis. Shumpert has a sore left knee but coach Mike Woodson says he probably will play in Game 4 against the Pacers. Indiana leads this Eastern Conference semifinal 2-1.

The setbacks come at a bad time for the Knicks, who have been struggling on offense. On Saturday, they shot 35 percent and made only three 3-pointers. They flirted with the franchise record for fewest points in a playoff game in an 82-71 loss.
