The Nuggets and Nets are closing in on a four-way trade that would send multiple draft picks, Derrick Favors and Andrei Kirilenko to the Nuggets in exchange for Carmelo Anthony.

Devin Harris would go to Charlotte and Boris Diaw to Utah in the proposed trade, which is not yet final.

One source close to the talks said that all the teams are "seriously engaged" after extensive discussions Thursday.

The deal would be contingent on Anthony agreeing to sign a long-term contract extension with the Nets, who are set to move to Brooklyn after playing the next two seasons in Newark.

One source told ESPN that Anthony's willingness to sign with the Nets is a potential obstacle to completion of the trade.
