COLUMBUS, Ohio — Ohio State football’s national title defense will come with a new face running the defense. The Buckeyes are losing defensive coordinator Jim Knowles. After three seasons in Columbus, he’s leaving to serve as Penn State’s defensive coordinator, according to multiple reports.

The Ohio State Buckeyes finished the season with a national championship, cementing head coach Ryan Day's status as one of the top coaches in college football. Day was joined by a pair of veteran assistants in offensive coordinator Chip Kelly and defensive coordinator Jim Knowles.

Knowles would fill the void on Penn State’s staff left by Tom Allen, who accepted the same position with Clemson earlier this month.
