The Thunder will once again be shorthanded in Game 4, as Jalen Williams has been downgraded to out with left hamstring soreness, Rylan Stiles of SI.com notes (via Twitter).
Oklahoma City took Game 3 by a score 123-108 without Williams and will try to replicate that success as the team looks to take a 3-1 lead over the Spurs heading back home.
The Thunder were already down one rotation player, as word broke on Saturday that they would be without breakout guard Ajay Mitchell due to a right soleus strain. Mitchell has started a majority of the games Williams has missed this postseason; with him sidelined, the Thunder will need to find another source of offense to help complement the rest of the starting lineup.
Cason Wallace will start in place of Williams, per Justin Martinez of The Oklahoman (via Twitter). Alex Caruso and Jared McCain have stepped up offensively throughout the series, and their contributions will be even more important with a pair of rotation regulars sidelined.
