Glen Davis out with upper back spasms

As if the week couldn't get any worse for the Los Angeles Clippers, Glen Davis left Sunday's game against the Oklahoma City Thunder with upper back spasms. He will not return to the court.

Prior to the game, it was announced that Blake Griffin will undergo elbow surgery on Feb. 9 and will miss four to six weeks of action. They were already shorthanded -- J.J. Redick was out with back spasms.
