While ESPN, like nearly every other US sports media outlet, has reported on the Meyer situation since the scandal broke open last week, it was Brett McMurphy, an independent reporter who was laid off by ESPN, who broke the news that suggested Meyer knew about the allegations against Smith.
Two weeks ago, Meyer told reporters that he had no previous knowledge of the 2015 incident involving Smith and his wife at the time, Courtney Smith. Smith said he discussed the 2015 allegations with Meyer and athletic director Gene Smith.
"While an assistant coach at Florida in 2009, I was aware that there was an issue in the personal life of Zach and Courtney Smith", Addazio said in a statement to the Boston Globe. "It's Urban Meyer, and people want to be a part of it to show that they support him".
Ohio State opened preseason practice on Friday and starts the season September 1 against Oregon State.
Offensive coordinator Ryan Day was named as the team's acting head coach while Meyer is on leave.
