We pretty much already knew this due to the timing of when his positive test was released, but now official:
Ohio State coach Ryan Day, one of several people within the Buckeyes program who tested positive for COVID-19 last week, won't be out of isolation in time to coach in Saturday's game at Michigan State if the Buckeyes are able to play, a school spokesman confirmed to ESPN on Tuesday.
Monday is the earliest Day, 41, can return if he meets the CDC guidelines, according to the school. Associate head coach and defensive line coach Larry Johnson will handle the coaching responsibilities on game day, but Ohio State's status remains uncertain.
