Tucker, 24, is 6-foot-3 and appeared in 14 games with the 76ers last season, averaging 2.3 points. He played 20 games with the Jazz the year before that.
Jones, 26, is 6-5 and has six games of NBA experience, all coming with the Lakers during the 2018-19 season.
Both players are expected to wind up with the Wisconsin Herd of the G League. Tucker’s first NBA contract actually came with the Bucks in 2019, so he has played for the Herd previously.
