The Cleveland Cavaliers have begun testing the trade market for Luol Deng.
Deng was acquired by the Cavaliers in a trade with the Chicago Bulls in January.
The Cavaliers have concerns about the odds of Deng re-signing with the team in free agency this offseason.
Ken Berger of CBS Sports reports that the Dallas Mavericks have called the Cavaliers on Deng. The Mavericks are a potential free agent suitor for Deng, but lack the assets to engage in serious talks with the Cavaliers.
