Trade talks between the Cavaliers and Wizards for Antawn Jamison have intensified on Tuesday, sources tell Yahoo!

The Cavaliers have yet to meet Washington's asking price, which is believed to include J.J. Hickson.

Brian Windhorst of the Cleveland Plain Dealer reports that the Celtics are also chasing Jamison, and testing interest in Rasheed Wallace in order to open a spot for Jamison.  But Windhorst cites sources who say that this scenario is unlikely for the Celtics.
