The San Antonio Spurs ruled starting guard De’Aaron Fox out for Game 1 of the Western Conference finals against the Oklahoma City Thunder on Monday, May 18, 2026, due to right ankle soreness. Despite Fox’s absence, the Spurs secured an epic double-overtime victory at the Paycom Center in Oklahoma City.
The Western Conference finals began with a significant roster adjustment for the San Antonio Spurs, who determined that De’Aaron Fox could not compete in Monday night’s series opener. Fox, a primary offensive engine for the Spurs, had been listed as questionable leading up to the game. After participating in the team’s morning shootaround and attempting a pregame workout approximately 90 minutes before tip-off, the medical staff and coaching personnel concluded that his right ankle was not sufficiently recovered for game action.
Status of the Spurs’ Backcourt
The decision to sideline Fox removed a player who has been a consistent contributor throughout the 2026 postseason. Entering the series against Oklahoma City, Fox maintained averages of 18.8 points and 5.8 assists over 33.3 minutes per game. Spurs head coach Mitch Johnson acknowledged the recurring nature of the injury, noting that the team anticipates the soreness will persist throughout the remainder of their playoff run.
It’s one of those deals where it’s not going away for as long as we’re playing, I don’t believe.
Mitch Johnson, San Antonio Spurs head coach
Despite the uncertainty surrounding his availability for the opening game, the Spurs have proven capable of adjusting to his absence. The team entered Monday with a 7-3 record in games played without Fox this season. His injury history this year has been limited, having missed only three games since sitting out the first eight contests of the regular season. The team’s depth chart has been tested throughout the year, requiring various rotations to maintain their standing in the Western Conference playoff bracket.
Thunder Roster Developments
While the Spurs managed the absence of their starting guard, the Oklahoma City Thunder welcomed back Jalen Williams. Williams had been sidelined since April 22 due to a Grade 1 left hamstring strain, forcing him to miss the entirety of the second-round sweep of the Los Angeles Lakers.
The return of Williams provides the Thunder with a versatile All-NBA forward capable of impacting the game as a playmaker, rebounder, and perimeter defender. Prior to his return on Monday, Williams had missed 55 of the team’s first 90 games, with his absences split between a right wrist issue and hamstring strains. During the six playoff games he missed, Ajay Mitchell stepped into the starting rotation and averaged 21 points. His reintegration into the Thunder lineup marked a significant tactical pivot for head coach Mark Daigneault as the team looked to counter San Antonio’s size and length in the paint.
Game 1 Outcome
The absence of Fox did not prevent the Spurs from capturing the series lead. In a highly competitive contest that required two overtime periods, the San Antonio Spurs defeated the Oklahoma City Thunder at the Paycom Center. Victor Wembanyama anchored the Spurs’ performance, finishing the game with 41 points, 24 rebounds, and three blocks. The intensity of the game, which extended well past the standard regulation period, underscored the high stakes of the 2026 Western Conference finals.
The victory gives San Antonio a 1-0 lead in the best-of-seven series, shifting the momentum in a matchup that had been anticipated as a test of the Thunder’s elite-level play against the Spurs’ interior presence. With the series now underway, the focus shifts to whether the additional rest provided by the double-overtime conclusion and the days between games will allow for a potential return for Fox in Game 2.
Contextual Stakes and Schedule
As the series moves forward, the availability of key personnel remains the primary variable for both organizations. The Spurs have utilized a rotational strategy that relies heavily on Wembanyama’s interior dominance to compensate for perimeter inconsistencies caused by Fox’s periodic unavailability. For the Thunder, the return of Williams is expected to provide the necessary spacing and defensive versatility to mitigate the impact of the Spurs’ frontcourt.
The schedule for the remainder of the series remains tight, with the teams preparing for a rapid turnaround between contests. The league’s playoff format requires both teams to manage player fatigue, particularly following a Game 1 that featured an extended double-overtime period. Coaches and medical staffs are currently evaluating the physical toll of the opener as they prepare their respective lineups for the next scheduled game. The Spurs, having successfully navigated the opening test on the road, look to maintain their series lead while monitoring the status of their starting guard’s right ankle soreness in the days leading up to the next tip-off. The league office continues to monitor injury reports to ensure compliance with reporting standards as the conference finals proceed.
