Williams will start Wednesday's game against the Spurs, Anthony Slater of ESPN.com reports.
With the Warriors being very shorthanded in the first leg of this back-to-back set, the two-way player will make his first start since the 2022-23 campaign with Portland. He's averaging 6.2 points and 1.8 rebounds across 13.3 minutes per tilt in 11 regular-season games thus far, though he should see a significant uptick in minutes against San Antonio.
