Green-Beckham was kicked off the Tigers after last season when he was investigated for a burglary in which he allegedly pushed a woman down several stairs at an apartment in Columbia. Green-Beckham was not charged in the incident.
During his tenure with Missouri, though, he was twice arrested for marijuana-related incidents.
Following his April 11 dismissal, Green-Beckham issued a statement to the St. Louis Post-Dispatch acknowledging his immaturity.
“I have been young and dumb,” the statement read. “I want to be better. During my suspension I’m entering counseling. With help, I know I can be stronger emotionally and spiritually.”
Green-Beckham was a five-star recruit and the nation’s top player in the 2012 recruiting class. The Sooners were in the hunt for Green-Beckham until very late in the process.
Green-Beckham was initially connected to a possible transfer to OU last month.
While Green-Beckham would likely have to sit out the 2014 season, he could receive a waiver that would allow him to play immediately.
The waiver is not without precedent, as LSU basketball player Anthony Hickey recently received a waiver allowing him to play immediately at Oklahoma State.
In two seasons with the Tigers, Green-Beckham had 87 catches for 1,278 yards and 17 touchdowns.
In the SEC title game against Auburn, Green-Beckham had six catches for 144 yards and two touchdowns.
