(MCT) — DENVER — The Bulls and Raptors engaged in trade talks centered on Carlos Boozer and Andrea Bargnani more than a week ago, according to two league sources.

ESPN.com’s Marc Stein first reported the talks, which a source told the Chicago Tribune the Bulls initiated and originally dismissed because of the Raptors’ desire to land the Lakers’ Pau Gasol. Though talks are not currently active, a source said the Raptors know the trade is available and could expand to include Nate Robinson and John Lucas III. Another source suggested it’s unlikely the Raptors would take on Boozer’s contract, which is $9.1 million more than Bargnani’s over the next two seasons.
