The Sooners have filled out their coaching staff.
According to The Athletic's Bruce Feldman, Oklahoma hired Arizona State defensive line coach Jamar Cain.
The program officially confirmed Cain's hiring on Friday afternoon.
Cain was with the Sun Devils since January 2019 after a stint with Fresno State for two seasons.
He has also served as a defensive assistant at North Dakota State and Ohio University.
With the hire, head coach Lincoln Riley has filled out his primary assistants. The program announced Wednesday the hire of DeMarco Murray as its running backs coach after Jay Boulware left for Texas recently.
The outside linebackers position was open after Ruffin McNeill stepped away from football to take care of his sick father.
