LOS ANGELES -- Tyson Chandler usually is one of the most accessible Knicks, willing to discuss almost anything. But he didn't want to talk about his injured left knee.

Chandler shook his head as he walked past reporters after the Knicks' 105-90 loss in Portland on Thursday night. He eventually stopped but said little, and he isn't sure he will be able to play Sunday afternoon against the Clippers.

"Maybe," he said. "We'll see."

Chandler wasn't beaming with confidence as he spoke, either.

He said he hasn't had any tests on his knee and feels "a lot better" than when he got hurt in Wednesday night's game in Denver. The Knicks said Chandler's knee is bruised and Mike Woodson called him day-to-day.

Chandler's rare reluctance to speak could mean he's concerned about his knee and doesn't want to say anything. The Knicks didn't practice Friday but will Saturday, and updates on the health of Chandler and Carmelo Anthony could be available then.

As they were in Portland, the Knicks could be without their two All-Stars Sunday when this five-game trip continues. The Knicks have lost the first three games by a combined 67 points.

"No matter if they come back or not, we got to figure out how to stop the bleeding," Jason Kidd said. "If they are out, we have to go with the group that we have in here and we feel we can stop the bleeding with that. When they do come back, that doesn't guarantee us anything, because we've had them and we lost. We've got to get out of this funk."

Anthony flew to Los Angeles and rejoined the Knicks after having the fluid drained from the back of his right knee. Woodson said he wasn't sure if Anthony can go through practice Saturday or play against the Clippers.

The Knicks said no structural damage was found in Anthony's knee, which has kept him out of four of their last six games. But his teammates are concerned after seeing Anthony remove himself from games twice in a 10-day span.

"I think we all are," J.R. Smith said. "We have to be. He's the star of our team. Depending on what the docs say, we have to patiently wait like everyone else and figure it out."

The Knicks hope the rest of their players hold up.

They already have lost Amar'e Stoudemire (right knee surgery) and Rasheed Wallace (left foot surgery) for the remainder of the regular season. Smith has been playing with a left knee and shin issue and Kenyon Martin bruised his right shin in Portland. Martin, whom the Knicks signed for the rest of the season Friday, is expected to play Sunday.

Kurt Thomas, 40, and Marcus Camby, 38, also have been thrust into more action because of injuries. The Knicks can't afford to have either break down as they wait for Anthony and Chandler to return.

"The starting block is to play hard," Smith said. "When we play hard, we can play with anybody, regardless of who's playing and who's not."
