Offensive coordinator Zak Hill resigned from his post at Arizona State over his role in alleged, widespread recruiting violations in the football program, multiple reports said Friday.
Hill was the fourth assistant coach to depart Herm Edwards' staff while the NCAA investigates the program. Wide receivers coach Prentice Gill and secondary coach Chris Hawkins were fired last week, and tight ends coach Adam Breneman also resigned, per reports.
The main allegations the NCAA is looking into are that Arizona State hosted high school recruits during a dead period brought about by COVID-19, and that coaches visited prospects and their families during the same dead period.
According to 247 Sports, Gill has appealed his firing and could bring about a wrongful termination claim.
Hill, 42, was the Sun Devils' offensive coordinator for two seasons after four years on Boise State's staff in a similar role.
Earlier this week, former NFL coach Brian Billick, who won a Super Bowl with the Baltimore Ravens, joined Edwards' staff at Arizona State as an offensive analyst and special adviser.
