Urban Meyer has been placed on paid administration leave.

Ohio State is investigating Courtney Smith's claims that several people close to Meyer knew of a 2015 allegation of domestic violence against her ex-husband, former Ohio State assistant football coach Zach Smith, who was fired in July.

Courtney Smith told college football reporter Brett McMurphy her allegations in a story posted on his Facebook page earlier Wednesday.

"All the [coaches'] wives knew," Smith told McMurphy. "They all did. Every single one."

On July 24, Urban Meyer denied knowing that Zach Smith had been accused of domestic violence in 2015, saying at Big Ten media days, "I was never told about anything." Meyer said the decision to fire Smith was a "very tough call."
