USC is making a change at quarterback, replacing starter Miller Moss with UNLV transfer Jayden Maiava, sources confirmed to ESPN.

After the Trojans lost four of their past five games and fell to 4-5 on the season, coach Lincoln Riley will opt to give the sophomore starting reps when they host Nebraska on Nov. 16. USC is currently on its second bye week of the season.

Moss began the season by leading the Trojans to a signature victory over LSU in Las Vegas, but he has regressed over the past few games.

Playing behind a shaky offensive line, Moss has made crucial mistakes of his own. In his past five games, the junior has thrown seven interceptions. Against Washington on Saturday, Moss threw three costly picks in a 26-21 loss.

In nine games as starter, Moss has thrown for 2,555 yards with 18 touchdowns and nine interceptions.

Maiava transferred to USC this offseason after a strong freshman campaign at UNLV during which he threw for 3,085 yards and 17 touchdowns. He completed 63.5 percent of his passes and added three rushing touchdowns.

Maiava is a more mobile option under center. In limited appearances this season, Maiava has showcased his ability to escape the pocket and make plays on the run. He has made eight completions for 66 yards and ran the ball three times for 27 yards, including a touchdown.

After backing up Heisman Trophy winner Caleb Williams for two seasons, Moss' first start came during the 2023 Holiday Bowl, where he threw for a bowl-record six touchdowns and staked his claim to be the starter in 2024.

Though the quarterback competition between Maiava and Moss extended into fall camp before the season, Riley was adamant throughout team practices that Moss was ahead.

Despite four losses in the past five games, Riley had remained outwardly steadfast in his confidence in Moss as the starter. At one point ahead of USC's matchup against Rutgers two weeks ago, Riley said Moss was "100%" the starter going forward.

USC beat Rutgers, but its loss at Washington puts it in danger of not securing a bowl berth. With three games remaining, the Trojans hope Maiava can provide a much-needed spark.
