Golden State Warriors center Andrew Bogut sprained his surgically repaired left ankle against the Oklahoma City Thunder on Thursday night.
The team said Bogut would not return. His status for Friday night's game at the Los Angeles Lakers was not immediately clear.
Bogut exited with 2:55 remaining in the first quarter against the Thunder. He went to the locker room for observation and did not return to the bench.
The 7-footer from Australia has missed 48 of 79 games this season, most due to the ankle he broke in January 2012 before coming over in a trade that sent Monta Ellis to Milwaukee. He had microfracture surgery on the ankle in April. Thursday night was his 19th straight game played.
The Warriors already have clinched a playoff berth.
