USC will be without a key defensive back for the first two quarters of the Trojans’ game against Nevada on Saturday.

The Pac-12 said in a statement Thursday that Christian Roland-Wallace, a transfer from Arizona, will sit the first half to serve a suspension, per the Arizona Daily Star’s Justin Spears. Roland-Wallace was involved in a fight and ejected at the end of the Wildcats’ game against rival Arizona State last season.

The suspension was presumably set to take effect during the Trojans’ victory against San Jose State last Saturday. However, Roland-Wallace played in that one and was credited with a tackle.

It’s unclear if USC will face any action from the NCAA for that decision.

Roland-Wallace was brought in via transfer in the offseason as USC looked to improve its defense. He was Arizona’s fourth-leading tackler in 2022 with 58 stops and recorded a team-high 6 passes defended. He also forced 2 fumbles.

That said, the Trojans will be without his services through the first half of their contest against the Wolf Pack on Saturday afternoon at the Coliseum. The game, the first between the two programs since 1929, kicks off at 3:30 p.m. PT and will be televised on the Pac-12 Network.
