San Antonio rules starting guard De’Aaron Fox out of Game 1 of the Western Conference finals against the Oklahoma City Thunder due to right ankle soreness. Fox tests the ankle at Monday morning shootaround and is on the court again roughly 90 minutes before tipoff, but he is ultimately unable to play, leaving the Spurs without their scheduled starting guard for the series opener. Oklahoma City, meanwhile, gets a key player back: guard Jalen Williams returns to the lineup after missing six games with a left hamstring strain. The return strengthens the Thunder’s rotation for the opening contest. With Fox sidelined and Williams available, both teams enter Game 1 with notable changes tied to recent injuries. The reports indicate the updates come from pregame team information and warm-up activity, with Fox speaking about trying to test the ankle but still being ruled out before tipoff.
