Maponga was the only Horned Frogs player to be named to the All-Big 12 team in the preseason and was on his way to living up to that honor before suffering the injury. He amassed 12 tackles, including a sack, and three quarterback hurries.
TCU is ranked No. 23 in the nation and is 2-1 in conference play heading into Saturday's home game. They'll have a real test in Texas Tech, which is ranked No. 17 and is 2-1 in the Big 12.
