(AP) -- The Nets are closing in on a deal to bring Carmelo Anthony to New Jersey. Talks on a three-team trade with the Denver Nuggets and Detroit Pistons are "advancing," a person with knowledge of the discussions told The Associated Press on Sunday.

The trade would reunite Chauncey Billups and Richard Hamilton in New Jersey along with Anthony, the person said on condition of anonymity because he wasn't authorized to publicly discuss the talks.

Although there has been progress, the person said there are potential roadblocks. The deal would fall apart if Anthony refused to sign a three-year, $65 million contract extension with the Nets. Billups also has said he would be reluctant to leave Denver.
