Upset by the Nets' handling of medical concerns that arose in his physical ? Shareef Abdur-Rahim said that he no longer wanted to join the franchise, but the team is expected to announce on Monday that it is going through with the deal.

Abdur-Rahim was courted heavily by the Nets, but was disillusioned by the team's last-second decision to seek additional medical opinions about scar tissue in his right knee.

When his feelings were published in yesterday's Post, Nets star Jason Kidd, coach Lawrence Frank and Thorn called Abdur-Rahim to rebuild the relationship, sources told The Post.

"Shareef is a good guy, and No. 1, he's a professional," said Thorn. "I understand there's some anxiety and trepidation when the possibility of not ending up with the team you chose arises. We feel we have all the information we need to make a decision within the next day or two."

The Nets have reason to be cautious since they are investing six years and $38 million in the deal. They sent copies of his MRI to three leading orthopedic surgeons and now must decide if they want to complete a sign-and-trade deal with the Trail Blazers.
