"We are pleased to welcome Dorial to the University of Oklahoma, where he is excited to continue his education and resume his playing career,” Stoops said. “Dorial understands the privilege and responsibilities of representing the Oklahoma Football program. He is a talented young man who is eager to get to work with the rest of our team in the classroom and on the field.”
Earlier the day, it was reported that Green-Beckham was on campus visiting coaches.
Green-Beckham was suspended and then dismissed from the Missouri program in April after being the focus of an assault investigation by the Columbia, Missouri, police department. Green-Beckham was not arrested or charged in the case.
