NORMAN — The next time Oklahoma tight end Jermaine Gresham plays in a football game, it will be in the NFL. Gresham, out this entire year after undergoing surgery to repair cartilage damage in his knee, will declare for the 2010 NFL Draft after this season. "Jermaine’s going to go into the draft,” coach Bob Stoops said Tuesday. Gresham, despite being a senior, had the option of coming back to OU for another season, since he played as a true freshman in 2006 and still had a redshirt year available. He had considered entering the draft last year, but decided to return to school even though most draft analysts projected that he would be a first-round pick. Gresham injured the knee on Sept. 1, the week of the season opener against Brigham Young. After sitting out that first game, doctors determined that Gresham would require season-ending knee surgery to stitch the cartilage back together. Doctors estimated Gresham’s recovery time would be about five months. If Gresham is able to stick by that timetable, he has a chance to be healthy for the NFL’s Scouting Combine in late February. Despite playing only three seasons, Gresham will go down as the most prolific tight end in Sooner history. While earning All-America honors last season, he caught 66 passes for 950 yards and 14 touchdowns, the second-most touchdown receptions by any player in school history.
