Cooper, who already returned for one extra year of eligibility after taking a redshirt due to an ankle injury in 2019, had already indicated before the end of the season that he did not plan to return to the Buckeyes for a sixth year of eligibility. He's among the Buckeyes who have accepted invitations to participate in next week's Senior Bowl.

While Cooper battled through his share of adversity in his Ohio State career, the Columbus native made it clear in his announcement that he has no regrets about his decision to spend the last five years with the Buckeyes.

“If I would've known all the struggles and challenges I've been through my career at Ohio State would I have still came? The answer is YES,” Cooper wrote.
