University of Oklahoma officials feel very confident about their chances to get wide receiver Dorial Green-Beckham approved for immediate eligibility with an NCAA waiver, sources told The Oklahoman.

OU still hasn’t filed the appeal yet, but plans to send it to the NCAA soon after they receive additional documentation from Missouri.

According to sources, OU will appeal using the so-called “run-off” waiver, created by the NCAA a couple years ago for players who were removed from their programs for reasons beyond their control. Oklahoma State’s basketball team added senior point guard Anthony Hickey, a three-year starter at LSU, and Hickey was granted immediate eligibility under the run-off rule.
