Jackson Jeffcoat out for season

AUSTIN, Texas -- Texas has lost one of its best defensive players for the year but not its quarterback.

Junior defensive end Jackson Jeffcoat suffered a right pectoral muscle rupture against Oklahoma and will have to undergo surgery to repair the damage, according to Texas trainer Kenny Boyd. Jeffcoat has been ruled out for the season.

Quarterback David Ash suffered a left wrist injury against Oklahoma. A fracture was not revealed in the X-rays, and Ash has not been ruled out for Saturday's game against Baylor.

Additionally, defensive tackle Brandon Moore (neck sprain) and junior tackle Donald Hawkins (ankle) will be evaluated during the week before a determination is made on their availability for the Baylor game.

The loss of Jeffcoat could prove to be devastating for Texas, which is 95th in the nation in rush defense and just gave up 677 yards to Oklahoma -- the most the program has allowed since 1950 -- and now faces Baylor and Nick Florence. Florence leads the nation in total offense with 404.40 yards per game.

Texas does have backups in Cedric Reed and Reggie Wilson. Both have played, with Wilson being the more productive of the two.

But Wilson's production most likely will not match that of Jeffcoat, who has been projected as an early-round NFL draft pick if he elects to come out. Jeffcoat has 11 tackles for loss, four sacks, six quarterback hurries and a fumble recovery for a touchdown. He also has forced two fumbles.

Jeffcoat missed all of spring practice because of surgery to repair his left pectoral muscle following the 2011 season.

As for Ash, Texas does have an experienced backup in Case McCoy. The junior come in for Ash in the fourth quarter against the Sooners and was 5 for 8 for 102 yards and two touchdowns. McCoy is 3-2 as a starter for Texas and, in his career, has completed 61 percent of his passes for 1,200 yards. He has 10 touchdowns and four interceptions.

Ash had thrown for an average of 300 yards per game in the three games previous to Oklahoma. He was 13 of 29 for 113 yards with two interceptions against the Sooners.
