Bogut was held out of the team's 107-101 overtime win over the San Antonio Spurs on Friday due to the back injury. Bogut underwent an MRI on his back but the team has yet to receive the results.
Bogut missed 43 games due to a stress facture in his back during the 2008-09 season and has also missed games due to back injuries in 2009-10 and 2010-11, according to Gate. The former No. 1 overall pick has only appeared in 12 games this season, as he's been recovering from left ankle surgery.
Bogut is averaging 7.1 points, 6.5 rebounds and 1.6 blocks in 22 minutes per game this season. The Warriors are 6-6 with Bogut in the lineup this season and 26-17 without him.
