Solomon suffered the injury during the second-quarter of the Wildcats' 56-30 loss to UCLA. Even before the concussion, Arizona's passing game struggled to move the ball against the Bruins. Solomon finished the game 4 of 10 for 55 yards and a touchdown before being replaced by senior Jerrard Randall. Randall completed only four of 16 passes.
Randall is more of a running threat at quarterback and Arizona is expected to focus on an option run attack against the Cardinal. Randall picked up 128 yards on 16 carries to go along with 136 yards from running back Nick Wilson.
The Wildcats suffered their first loss of the season against UCLA and dropped from No. 16 out of the AP top 25.
