Senior defensive tackle Ashton Dorsey has decided to transfer, Texas announced Tuesday morning.
Head coach Mack Brown said Monday that Dorsey would not play in the Longhorns' season opener against New Mexico State on Saturday due to a sore calf muscle. He had not practiced for the last week.
Dorsey's absence leaves Texas with just three defensive tackles on its roster that have any experience at the college level. Sophomore Malcom Brown will make his first career start this weekend while senior Chris Whaley and junior Desmond Jackson should also see significant playing time.
Mack Brown said Monday that redshirt freshmen defensive tackles Hassan Ridgeway and Alex Norman could also see the field Saturday. Both are likely to get even more playing time beyond this weekend's opener with Dorsey gone.
A 6-foot-2, 295-pounder from Tyler, Dorsey played in 30 games for the Longhorns, making six starts. He made 28 tackles last season, 10 for loss, the third-most on the team. He missed four of the final five games in 2012, two because of a calf injury and the last two because of a concussion. Dorsey made 54 career tackles, 18 for loss, including one sack and one forced fumble.
