Ryan Houston ran for a career-high 164 yards and Jheranie Boyd scored the clinching touchdown midway through the fourth quarter to help North Carolina beat Duke 19-6 on Saturday.
Charles Brown also came up with a key interception late in the third quarter as part of a dominating defensive performance for the Tar Heels (6-3, 2-3 Atlantic Coast Conference), who shut down Thad Lewis and the prolific passing attack that had carried the Blue Devils (5-4, 3-2) to three straight victories.
