Iman Shumpert didn't practice Monday due to soreness in his surgically repaired left knee. He expects to play in Game 4 Tuesday night, but could be slowed or limited.

Shumpert fell twice in Game 3 against Indiana, and one of the times he said his knee "bent back awkward." He remained in the game, but started feeling soreness Sunday, and said it's bruised. Mike Woodson said Shumpert also was held out of practice Sunday.

"In my mind, I'm playing," Shumpert said. "Unless I get out there and I can't do what I'm supposed to do, I don't think it will stop me from playing."

The Knicks already are less than 100 percent. J.R. Smith and Kenyon Martin remain quarantined with a virus. Woodson called Smith a game-time decision.

Shumpert has been the Knicks' best defender this postseason. They can't afford to be without him in this critical game. The Knicks trail Indiana 2-1 in this Eastern Conference semifinal.

Woodson and Shumpert both said it's not related to the surgery he had last May to repair a torn ACL. Shumpert hasn't undergone an MRI. But Woodson said Shumpert's extended minutes lately may have contributed to the soreness, which may not be a good sign.

"His minutes have jumped some," Woodson said.

Smith and Martin were at the hotel instead of at practice for the second straight day. The Knicks are trying to keep them from infecting other players.

Woodson said Martin's symptoms aren't as severe as Smith's but "heading in that direction." Smith had a 102-degree fever Saturday. He played in Game 3 and shot 4-for-12 with nine points.

"I haven't seen J.R.," Carmelo Anthony said. "They're kind of keeping him away from everybody because of his health. But I'm pretty sure from what I'm hearing he'll be ready for [tonight]."
