NORMAN, Okla. — Oklahoma coach Jeff Capel says preseason All-American Blake Griffin is out for Monday night's game against No. 15 Kansas.

Griffin is still recovering from a concussion sustained in Oklahoma's loss Saturday at Texas. The sophomore is the third-ranked Sooners' leading scorer and rebounder.

Capel says he doesn't know when Griffin will return. Griffin is averaging 22 points and 13.8 rebounds per game and leads the country with 22 double-doubles.

Griffin was hurt Saturday when he caught an inadvertent shot to the face from the open hand of Dexter Pittman, Texas' 300-pound center.
