Meyer was placed on paid administrative leave Wednesday after published reports alleged he knew of ongoing domestic problems between wide receivers coach Zach Smith and his now-ex-wife, Courtney.
Smith was fired last week after violating a domestic protection order.
At that time, Meyer said he knew of an incident between the Smiths in 2009 when Zach Smith worked for Meyer at Florida but said his staffers told him a 2015 incident that recently surfaced did not happen.

Courtney Smith subsequently told national college football reporter Brett McMurphy and the website Stadium that she had told Meyer's wife, Shelley, about the 2015 incident.
While Courtney said she believed Urban Meyer knew -- in part because the wives of other coaches also knew -- but she was not certain he did.
Ohio State began practice for the 2018 season Friday morning.
