Roy Williams unsure if Joel Berry will play vs. Arkansas

Arkansas' chances for an upset over No. 1 North Carolina could be improving.

Tar Heels head coach Roy Williams said he's unsure if guard Joel Berry will be able to play Sunday because of an ankle injury, according to Jonathan Jones of Sports Illustrated. Williams added that Berry was being held out of practice Saturday.

The junior injured the ankle in a first-round win over Texas Southern, but returned to the game despite North Carolina owning a lopsided lead.

Berry ranked second on the Tar Heels in scoring this season, averaging more than 14 points per game. Arkansas should prove to be a much tougher challenge than Texas Southern, so if Berry can't go, the Razorbacks might have a shot at pulling off a shocker.
