OU's Gresham has cartilage damage, won't play against BYU

Oklahoma All-America tight end Jermaine Gresham has cartilage damage to his right knee and will not play Saturday against BYU, but the extent and treatment of the injury are currently uncertain.

According to a press release today from the university, the "evaluation process is continuing" regarding Gresham's playing status this season.

Rumors began swirling Wednesday night, and Internet message boards became clogged with thousands of posts into the early morning hours.

It's not known when or how the injury occurred. Gresham was seen by reporters on Tuesday night after practice, still in full pads, looking at pictures of former teammates hanging in a hallway of the team's renovated Switzer Center.

OU offensive Kevin Wilson will have Trent Ratterree and James Hanna listed on the depth chart at tight end, according to the press release from OU.

Gresham is a senior from Ardmore who returned for his final season at OU instead of testing the NFL waters, where many analysts think he would have been a first-round draft pick last April.

Gresham is the Sooners' leading receiver from 2008's record-setting offense. He caught 66 passes for 950 yards and 14 touchdowns last season.
