(REUTERS) - Oklahoma City Thunder guard Russell Westbrook was ruled out for Tuesday night's opener at the Golden State Warriors as he continues to recover from arthroscopic surgery on his right knee.
Westbrook underwent the procedure on Sept. 12 and was slated to be re-evaluated in four weeks, which was last Wednesday, but coach Billy Donovan told reporters Tuesday the seven-time All-Star would miss the opener. Dennis Schroder will likely start in Westbrook's absence.
Meanwhile, big man Steven Adams could also miss the opener due to lower back stiffness, which kept him out of Monday's practice. Donovan indicated Adams will be a game-time decision against Golden State.
Westbrook, who turns 30 in November, has missed just four games total over the last three seasons. He holds career averages of 23.0 points, 8.2 assists and 6.6 rebounds per game in 748 games, averaging a triple-double in each of the last two seasons and winning the 2016-17 MVP award.
Adams, 25, averaged 13.9 points and 9.0 rebounds per game while starting 76 games last season.
The Thunder's second game of the season is Friday at the L.A. Clippers.
