Oklahoma coach Lincoln Riley revealed his starting quarterback for 2020 would be redshirt freshman Spencer Rattler.
Riley made the announcement Tuesday as the Sooners prepare for their Sept. 12 season opener against Missouri State.
A five-star recruit from Arizona, Rattler appeared in three games last season but was declared a redshirt.
Rattler is the fourth different quarterback to start for Oklahoma in the past four seasons. Baker Mayfield, Kyler Murray and Jalen Hurts were the starters in the past three openers.
Redshirt sophomore Tanner Mordecai missed about three-fourths of camp, Riley said Tuesday.
