Injuries have played a major role in the Big 12 through the first half of the season and they’ll continue to impact the conference title race down the stretch. Baylor is the lone squad in the top half of the Big 12 that has escaped the injury bug relatively unscathed.

1. TCU: The Horned Frogs have watched quarterback Casey Pachall and defensive end Devonte Fields, arguably their top players on each side of the ball, go down. Pachall (forearm) could return soon but Fields (foot) is lost for the season. It’s easy to imagine the Horned Frogs offense, which has looked lost and has averaged just 97.4 yards in the first half in the past five games, as much improved with Pachall under center.

2. Texas: Another team that has lost a major contributor on both sides of the ball, the Longhorns hope to get quarterback David Ash (head) back at some point this season and have lost defensive leader Jordan Hicks (Achilles) for the season. Add in nicks and bruises to playmakers Daje Johnson and Mike Davis and success has been much harder to come by for Texas.

3. Oklahoma: The Sooners lost linebacker Corey Nelson (pectoral) and defensive tackle Jordan Phillips (back), two of their top defenders, in back-to-back weeks. Nelson's leadership is sorely missed and Phillips' strength in the middle is hard to replace. OU is still scrambling to replace the duo, which is a scary thought with Texas Tech and Baylor set to test the defense.
