A concussion will keep the true freshman out of action on Saturday

When the Texas Longhorns take the field against the No. 8 TCU Horned Frogs on Saturday, they’ll do so without true freshman running back Toneil Carter, who has officially been ruled out as he continues to work through concussion protocol, Tom Herman announced on Thursday.

Carter played a significant role last week in the Longhorns 38-7 win over Baylor, rushing for career highs with 15 carries for 70 yards and a touchdown, but he suffered a concussion towards the end of the game and has since been evaluated and limited in practice.

In 37 carries this season, Carter has rushed for 181 yards and two touchdowns on a team-best 4.9 yards per carry. Carter appeared to be in place to secure the Longhorns starting running back role going forward.

Although Carter is out, quarterback Sam Ehlinger, center Zach Shackelford and running back Kyle Porter will all reportedly be available.

Despite Ehlinger joining the mix once again, Herman said Shane Buechele took the bulk of the first-team reps this week and that Jerrod Heard took reps with the quarterbacks, as well.

Buechele, Ehlinger and Heard may all see time at quarterback on Saturday in Fort Worth.
