Davis: Yates 'undergoing further evaluation' Posted Sep 22, 2008 Butch Davis didn't have much to say Sunday evening about the fate of North Carolina quarterback T.J. Yates. "He's receiving treatment and undergoing further evaluation.". Yates injured his left ankle midway through the third quarter of the Tar Heels' 20-17 loss to the Hokies on Saturday when he was clipped from behind. Yates stayed in for one more play before deciding his ankle needed medical attention. (Durham Herald-Sun)
