Dallas will send Utah’s 2020 second-round pick to the Warriors.
Cauley-Stein, 26, signed a two-year $4.4 million deal with a player option for the second season with Golden State last summer. In 41 games (37 starts), Cauley-Stein averaged 7.9 points, 6.2 rebounds, 1.5 assists and 1.2 blocks in 22.9 minutes per game.
The move frees up a roster spot for the Warriors and creates an additional $2.1 million in space under the hard cap. Golden State can use the roster spot and cap space to promote one of their two-way contract players — guard Ky Bowman or center Marquese Chriss — to a standard contract.
Earlier on Friday, the Mavericks traded rookie Isaiah Roby to the Thunder for center Justin Patton, who they waived to clear a roster spot. For Dallas, they acquire a center after Dwight Powell suffered a season-ending Achilles tear against the Clippers this week.
