Oklahoma sophomore quarterback Jackson Arnold will enter the transfer portal, according to multiple reports on Wednesday.

A five-star recruit in 2023 out of Denton, Texas, Arnold began this season as the starter, lost his spot and later regained it as the Sooners went 6-6.

Monday is the first day that underclassmen can transfer during the winter portal window.

Arnold completed 154 of 246 passes (62.6 percent) for 1,421 yards, 12 touchdowns and three interceptions in 10 games. He also ran the ball 150 times for 444 yards and three TDs, including 25 attempts for 131 yards in the Sooners’ 24-3 win over Alabama on Nov. 23.

As a freshman last season playing behind Dillon Gabriel, Arnold appeared in seven games and was 44 of 69 (63.8 percent) for 563 yards, four TDs and three picks.

A former Gatorade Texas Player of the Year, Arnold started for Oklahoma in the Alamo Bowl last December, when the Sooners lost 38-24 to Arizona.

He was QB1 for the 2024 campaign, but three early turnovers caused him to be pulled in a 25-15 defeat to Tennessee on Sept. 21 and replaced by true freshman Michael Hawkins Jr.

Arnold came off the bench to replace Hawkins in a 35-9 loss to South Carolina on Oct. 19, and head coach Brent Venables afterward fired offensive coordinator Seth Littrell.

Co-offensive coordinator Joe Jon Finley became the interim play-caller. Venables filled the position permanently on Monday by hiring Washington State OC Ben Arbuckle, who could bring Cougars QB John Mateer with him to Norman, Okla.
