Williams (undisclosed) is out for Thursday's preseason game against the Hawks, Matt Guzman of SI.com reports.
Williams won't be an option for this contest, but the big man isn't likely to play a big role with the Spurs anytime soon. He's expected to play for the Austin Spurs in the G League in the 2026-27 campaign. His next chance to play in the preseason will come against the Suns on Saturday.
