Williams (abdomen) is in the starting lineup for Saturday's Game 4 against the Thunder, Earl K. Sneed of Mavs.com reports.
Analysis:
Coach Rick Carlisle said he expected Williams to play earlier Saturday, so it comes as no surprise he'll be available. Williams will move back into the starting lineup, pushing J.J. Barea back into a bench role. The Mavericks will likely look to limit Williams' minutes a bit, so that's something to keep in mind moving forward. With Williams back in the lineup, Barea, Raymond Felton and Devin Harris could all see a slight hit to their playing time.
