UNC athletic director Bubba Cunningham and head football coach Larry Fedora have officially apologized to Duke University after the Tar Heel football team did at least $10,000 worth of damage to Duke’s visiting locker room after Thursday night’s football game.

The Tar Heels won that game 45-20, and as per tradition, they got to spray-paint the Victory Bell with the team colors. But the players reportedly took the spray paint with them into the locker room – and proceeded to spray paint the walls and carpets as well.

UNC officials have said they’ll pay for repairs; estimates of the damage have run as high as $25,000.

Fedora and Cunningham issued an official statement of apology which reads:

“We would like to apologize to the Duke Football program and Duke University for some inappropriate actions after last Thursday night’s game in Durham. Our team took the celebration too far when they were painting the bell, resulting in damage to some of the facilities at Duke. We take full responsibility for our actions and will be paying for all costs associated with the cleanup. We view this as a rivalry built on mutual respect and we expect our players to behave better in a way that is more befitting of the rivalry.”

Larry Fedora also reportedly called Duke head coach David Cutcliffe to apologize personally.
