Nebraska is set to promote John Butler to defensive coordinator as part of a staff reshaping on that side of the ball, sources told ESPN's Pete Thamel.
Butler, who serves as Nebraska's secondary coach and defensive pass game coordinator, had already been named the team's interim defensive coordinator for the team's game against Boston College in the Bad Boy Mowers Pinstripe Bowl in New York. He will replace Tony White, who left last week to become defensive coordinator at Florida State. Butler served as Penn State's defensive coordinator in 2013 and then followed coach Bill O'Brien to the Houston Texans, where he coached the secondary from 2014 to 2017.
