Henry Frazier was put on paid leave after his May arrest. He was charged with misdemeanor assault on a female after a heated argument with his wife.
As of Monday, the university reinstated Frazier, and he expects to be practicing with the team as early as this week.
"When a university hires a football coach, they hire his entire family. In a million years, I would've never thought this would happen to me or my family," said Frazier. "I'd like to formally apologize to my family, the university and its supporters."
Court records show Frazier is participating in an abuse treatment program in exchange for a dismissed charge.
