NORMAN, Okla. - After a Saturday night MRI revealed a partially torn medial meniscus in his right knee, Oklahoma freshman forward Blake Griffin underwent arthroscopic surgery Sunday morning and is expected to return to action sometime during the postseason. 

Griffin injured the knee with 15:15 remaining in the first half of Saturday's 64-37 win over Texas A&M when he fell to the floor after getting tangled with Aggies' forward Bryan Davis.  Griffin went to the bench 18 seconds later and returned to the court with 4:49 left in the half.  He finished the game with 13 points and a game-high-tying eight rebounds in 23 minutes.  He scored all of his points and grabbed seven of his eight boards after sustaining the injury. 

On Jan. 14, Griffin sustained a sprained medial collateral ligament in his left knee with 15:10 left in the first half at Kansas.  He missed the remainder of that contest, as well as OU's next game against Texas Tech. 

The Sooners (19-10 overall, 7-7 Big 12) are in a four-way tie for fifth place in the league race and have two regular season games remaining.  They play at Oklahoma State (16-12, 7-7) on Wednesday at 7 p.m. CST before returning home to face Missouri (15-14, 5-9) on Saturday at 2:30 p.m.  The Big 12 Championship will be held March 13-16 in Kansas City, Mo.
