Ryan Day will have some very familiar competition in the Big 10 soon.

The son of the Ohio State football coach, R.J. Day, announced his commitment to Northwestern for the Class of 2027 on Sunday.

Northwestern plays in the same conference as Ohio State and the schools will face each other.

R.J. Day, a 6-foot-1, 205-pound quarterback from — not surprisingly — Columbus, Ohio, has started for three years at St. Francis DeSales HS as he heads towards his senior season.

According to reports, the younger Day had other offers from Purdue, Syracuse, Cincinnati and South Florida, as well as others.

Northwestern has eight quarterbacks on head coach David Braun’s roster.

And the offensive coordinator for the Wildcats is Chip Kelly, who served in the same role for Ryan Day at Ohio State when the Buckeyes won the title in 2024.

Kelly, the former head coach at UCLA and Oregon, was also the offensive coordinator at New Hampshire when Ryan Day was the team captain from 1998-2001. 

Most recently, Kelly was the OC with the Las Vegas Raiders before he took the job with Northwestern.

“It’s really surreal when you think about the relationships that we’ve had with those two as a family over the years,” R.J. Day told ESPN earlier this month. “Coach Kelly coached my dad in college, so that adds another layer to it.”
