Ryan Day is closing out his first week as head coach at Ohio State and there’s already been some significant staff changes in that time.

Among the many moves in Columbus, the most recent is that linebackers coach Bill Davis will not be returning to his post for the 2019 season. There was some speculation that he and the program may part ways, and he confirmed the move on Tuesday.

Davis released a statement through his Twitter account.

“Following a great season going 13-1 and winning our 2nd Big 10 Championship , my family and I took a few days to discuss our future,” Davis wrote. “We are grateful for our time at The Ohio State University and have enjoyed being a part of Buckeye Nation as well as an elite group of players and staff. After passing on previous opportunities we have decided to return to the NFL. Coach Day and I have mutually agreed he should plan his staff without me. We are excited for Coach Day and we will continue to cheer for the success of Buckeye Nation. Thank you! Go Bucks!”

Davis was on Ohio State’s staff for thee seasons, joining in 2016 as an analyst. He then became the linebackers coach in 2017, where he spent the last two years.

Davis has extensive experience in the NFL and Ohio State was his first collegiate stop since serving as a graduate assistant at Michigan State in 1991.

Replacing Davis will be Michigan linebackers coach Al Washington, according to reports. Washington served on the Wolverines staff just one season before returning to his hometown of Columbus.
