CHAPEL HILL, N.C. (AP) North Carolina won't have defensive end Tomari Fox this season after he lost an NCAA appeal of his punishment for consuming a banned substance.

Coach Mack Brown announced Tuesday that Fox is ineligible. The player drank a non-approved over-the-counter pre-workout beverage last year in what Brown described as an inadvertent mistake.

"He walked immediately to his locker and pulled what he was drinking out and said, `Coach, I bought this over at the grocery store,'" Brown said. "And I didn't think there was anything wrong with it. ... I think it's unfair for him.
