Withers has led the Tar Heels to a 7-5 record on the season. He replaced Butch Davis, who was fired on July 27.
Prior to taking over as head coach, Withers was hired as North Carolina's defensive coordinator in 2008. He was a DC for the Minnesota Golden Gophers in 2007 and an assistant with the NFL's Tennessee Titans and college football's Texas Longhorns and Louisville Cardinals.
Withers previously said he's had a lot of fun coaching the team through the remainder of the season.
"It’s been a blast. It really has. They didn’t bat an eye one bit...I didn’t know how they would react initially, but they just kind of came to work. Once we got three or four days into it, it was like, ‘OK, here we go.’ As coaches, we had to respond because they did. Again, I’m as proud of this football team as any that I’ve ever been on."
