A freshman from Cincinnati, Johnson is a three-star prospect from LaSalle High School who was the No. 13 senior in the state last season according to 247Sports Composite rankings.
Ohio State has no shortage of safeties, though there is still competition for playing time at both deep safety and cover safety.
Though he was a three-star prospect, Johnson had multiple Power 5 offers including Indiana, Kentucky and Michigan State.
Unlike most of his class, he did not join the program this summer, but Johnson arrived to a defensive backs room with a unique mix of veterans still looking to maximize themselves and unproven youngsters hoping to take their jobs.
Veterans Josh Proctor and Marcus Hooker both have starting experience at deep safety, where sophomore Bryson Shaw is also in the mix.
Senior Marcus Williamson, sophomore Lathan Ransom and redshirt freshman Cam Martinez are among the competitors at the other safety spot, which typically has lined up in the box the past two seasons but requires the ability to cover, blitz and stop the run.
The offensive line also lost some potential depth this week when Ryan Jacoby entered the transfer portal.
Bucknuts.com was the first to report he is looking elsewhere for playing time after two-plus years at Ohio State.
The 6-4, 305-pound junior from Mentor enrolled early in 2019 but never cracked the lineup.
He was a four-star prospect in his recruiting class.
