Trey Franks was a valuable return man for Oklahoma last season as a redshirt junior but will not be back with the Sooners next season.
Franks has graduated from school and chose not to return for his final season of eligibility, OU assistant athletic director for communications Pete Moris said.
Franks sat out the 2012 season after being suspended but returned last year, starting the season at defensive back before moving to wide receiver before the Texas Tech game on Oct. 26.
He had five returns for 118 yards last season. He was to be the Sooners only player back who returned kicks last year.
Franks played in all but one game this season, with six tackles and a fumble recovery. He did not have a catch after moving to offense.
For his career, Franks finishes with 51 catches for 459 yards and a touchdown and 32 kick returns for an average of 23.7 yards.
