Ohio State officially expanded its coaching staff on Monday when the Buckeyes hired Alex Grinch as its 10th assistant coach.
Grinch comes to Columbus from Washington State, where he served as defensive coordinator and secondary coach for the past three years.
Grinch's specific role on Ohio State's coaching staff has not yet been announced, but Fox Sports' Bruce Feldman reported last week that Grinch will be a co-defensive coordinator.
"I am pleased to announce the addition of Alex Grinch to our coaching staff," Ohio State head coach Urban Meyer said. "I am very impressed with his body of work while at Washington State, as many others were, and am happy he chose to come home to Ohio to become a part of our Buckeye coaching staff.
