With the results of his MRI pending, Jazz forward Marvin Williams wasn’t on the Utah Jazz bench for Friday night’s game against the Los Angeles Clippers.

Williams missed practice Thursday with a lower back strain and had been scheduled for an examination the same day. Instead, the MRI was pushed back to Friday morning and the results were not available before game time, Utah Jazz coach Ty Corbin said.

"We don’t want to put him out there until we get official word that everything is good," the coach said.

Williams, 27, has had some back issues in the past.

He missed one game in 2006-07 with back spasms. He missed 16 games in the 2008-09 season with a lower back injury. On Dec. 29, 2010, he landed on his back after attempting to block a shot and did not play again until Jan. 26, 2011, missing 11 games over that time.

And in June 2011, Williams had "minor surgery on his lower back to alleviate the pain from a bulging disk," according to an ESPN report, and spent about two months that summer in recovery.
