USC third-string quarterback Jack Sears will start against Arizona State on Saturday, the school announced.
The announcement comes a day after USC coach Clay Helton said starter JT Daniels was "50-50 at best" to clear the concussion protocol after suffering a concussion against Utah on Saturday. Helton previously said that if Daniels was cleared medically, he would start, indicating the true freshman will not be available in relief of Sears. USC will also be without backup Matt Fink, who fractured three ribs in the 41-28 loss to the Utes and will miss a few weeks.
