Oklahoma City Thunder forward Jalen Williams (Hamstring) and San Antonio Spurs guard Dylan Harper (leg) both left left Wednesday’s Western Conference finals Game 2 and didn’t return.

Williams left the court after playing seven minutes in the first quarter and did not return before halftime.

Cason Wallace replaced him in the starting lineup in the third quarter, and the Thunder ruled Williams out shortly after the quarter started with hamstring tightness.

The NBC broadcast showed Williams with a wrap around the same left hamstring that sidelined him earlier in the playoffs for six games.

Harper, meanwhile, grabbed his right leg after falling in the third quarter from a collision with Chet Holmgren.

He limped to the locker room, and the Thunder ruled him out before the start of the fourth quarter.

Williams missed Oklahoma City’s entire four-game second-round series against the Los Angeles Lakers with the injury, but returned for Game 1 Monday night against the Spurs, posting 26 points and 7 rebounds in 37 minutes.

An All-NBA player and a key to Oklahoma City’s run to last season’s NBA championship, Williams is critical to Oklahoma City’s chances against Victor Wembanyama and the Spurs.

Harper is playing in place of injured starter De’Aaron Fox (ankle) and thrived in San Antonio’s Game 2 win. Both players are key to their respective teams.
