Sources: Tristan Thompson set to sign with Cavs in 3-year deal

— -- Restricted free agent Tristan Thompson's agent will have the forward sign a three-year, $53 million contract with the Cleveland Cavaliers, league sources confirmed to ESPN's Chris Broussard.

Cleveland GM David Griffin, however, called news of any pending signing "untrue" and said the specific contract terms agent Rich Paul has instructed his client to sign have "never been discussed."

Thompson is of particular priority to the Cavaliers, who went to the NBA Finals this past season. He has appeared in 308 consecutive games for Cleveland, has averaged 10.1 points and 8.4 rebounds over his four-year career and saw his stock soar by averaging 9.6 points and 10.8 rebounds in this year's playoffs.
