Harrison Barnes practiced between 20 and 25 minutes on Monday and reported no setbacks on his left ankle as the Tar Heels prepare to face Duke on Wednesday.

"My ankle's great, and I'll be ready to go against Duke," Barnes said during a guest appearance on coach Roy Williams' radio show.

Barnes sprained his left ankle during a win at Wake Forest last week, then re-sprained it in a close win against Maryland on Saturday. Barnes finished with 18 points and made two important shots during the second half of the come-from-behind victory over the Terps.

"I think he showed some big-time toughness," coach Roy Williams said.
