EAST RUTHERFORD, N.J. (AP) An examination of Jason Kidd's left knee showed no new injuries, but the New Jersey Nets' All-Star guard remains in pain and is sidelined indefinitely.

``What we've revealed is that there is no significant change,'' Nets coach Lawrence Frank said Monday of the most recent MRI exam. ``It's being classified as the same. He went to see the doctor again today and we'll see what course they tell him to take. It means more what the doctors say. The good news is that the MRI results aren't worse. The bad news is that he's still in a lot of pain.''

Frank said he wouldn't put a timetable on Kidd's return.

``I can't begin to speculate and I'm not going to be a fortune teller, but if it's extended, then we're going to have to deal with it as a team,'' Frank said. ``We'll just pray for his health and know for sure in three or four days. I want to see what the doctor has to say.''

Kidd said Sunday that if he needs knee surgery, he'll wait until after the Nets are eliminated in the NBA playoffs. Barring a total collapse, the Nets appear a lock to win the Atlantic Division and get the second seed in the Eastern Conference.

Kidd was placed on the injured list Friday with a bone bruise. He was not at Monday's practice before the team headed to Chicago.

``I didn't think the news was going to get worse,'' forward Richard Jefferson said. ``I just figured that he was going to take some time off and get healthy. I'm not going to get worried about it. If Jason comes back, he does. If he doesn't, he doesn't.

``But I'm an optimistic idiot. It's not `What if?' We're not dealing with ifs. He's planning on coming back.''

Lucious Harris has moved from reserve into the starting rotation in Kidd's absence.

``If he's out for the year, then it's going to be a very big hole to fill,'' Harris said. ``We'll all have to step our games up that much more. It's kind of a big blow, but I'd rather they be out now and come back healthy.''

All-Star power forward Kenyon Martin has tendinitis in his left knee and will not play Tuesday night against the Bulls. The Nets lost to Dallas on Sunday without Kidd and Martin.

Martin performed resistance exercises after practice Monday, but said he has no timetable for a return.

``It's calmed down a lot and gotten better, but I still need a little more rest,'' Martin said. ``When I feel ready to play, I'll play. I'm not going to come back and try and then set it back and it could be another week. I want to play. I don't want to sit out, but I have to sit out to get better.''

The Nets signed free agent point guard Anthony Goldwire to a 10-day contract. Goldwire has had stints with Charlotte, Denver, San Antonio, Washington and Minnesota, with career averages of 6.6 points and 2.9 assists per game. He has had two 10-day contracts with Minnesota this season and recently had a 10-day contract with Milwaukee.

The Nets also put Hubert Davis on the injured list with patella tendinitis of the left knee.
