A person with knowledge of the decision says Washington State defensive coordinator Alex Grinch is leaving the Cougars and joining Ohio State as an assistant coach.
The person spoke to The Associated Press Thursday on condition anonymity because the deal was still being finalized. Ohio State spokesman Jerry Emig says there would be no announcement on the addition of a 10th assistant coach on Urban Meyer's staff until next week at earliest. A new NCAA rule goes into effect after this season that allows FBS teams to expand staffs to 10 full-time assistant coaches.
Sports Illustrated first reported Grinch was heading to Ohio State.
Grinch, an Ohio native who played at Division III powerhouse Mount Union, has been with Washington State since 2015.
