Warriors coach Mark Jackson said Bogut was not expected to make the trip to Los Angeles for Friday night's game against the Lakers.
Bogut exited Golden State's 116-97 loss with 2:55 remaining in the first quarter. 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 last April. Thursday night was his 19th straight game played.
The Warriors already have clinched a playoff berth.
