Oklahoma is benching quarterback Jackson Arnold and turning to true freshman Michael Hawkins Jr. for its Saturday road game against Auburn, coach Brent Venables said Monday during his weekly coaches show.

Arnold, a sophomore, completed 61 of 102 passes for 538 yards, seven touchdowns and three interceptions in the first four games of the season, leading the Sooners to a 3-1 record. He also rushed for 138 yards and a pair of scores.

Oklahoma benched Arnold on Saturday during a 25-15 home loss to then-No. 6 Tennessee after the signal-caller hit on just 7 of 16 passes for 54 yards and a pick. Hawkins took over, throwing for 132 yards and a TD on 11-of-18 passing.

The Sooners, who were ranked 15th in the nation ahead of the meeting with the Volunteers, dropped to No. 21 this week.

Hawkins was rated as a three-star recruit by 247Sports.
