According to the report, Texas head coach Charlie Strong said that Ash experienced "headaches and dizziness" the night after Texas' 38-7 win over North Texas.
If confirmed, this would be Ash's second concussion at Texas. The junior missed most of last season after suffering a concussion in Provo last season against the Cougars. Unfortunately, Ash's football future is in doubt, particularly if this does turn out to be a second concussion.
This is the second major injury for the Longhorns from the North Texas game. Fifth-year senior center Dominic Espinosa broke his right ankle against the Mean Green and will not play against the Cougars.
Tyrone Swoopes will start at quarterback against the Cougars on Saturday. The sophomore saw limited action last season as a backup, playing in six games in 2013. This will be his first career start.
