Williams (rest) is available for Tuesday's preseason game against Indiana, Justin Martinez of The Oklahoman reports.
Williams was one of numerous Thunder regulars who didn't join the team for Monday's loss to the Hawks, but he'll return to the lineup in the second half of this back-to-back set. With the star forward back in action, Otega Oweh, Brooks Barnhizer and Zhaire Smith will likely see fewer minutes.
