A separate report from RealGM's Shams Charania said that Sanders, who is in the second season of a four-year, $44 million contract, is expected to receive $13 million.
A report last month said that during the suspension Sanders intended to handle personal issues and learn to live without using marijuana.
Sanders has not played since Dec. 23. He was suspended five games in April 2014 for violating the league's anti-drug program.
Over 27 games this season, Sanders averaged 7.3 points, 6.1 rebounds and 1.4 blocks. The Bucks currently sit in sixth place in the Eastern Conference with a 30-23 record.
