UNC's Williams suffering vertigo

SAN DIEGO -- UNC coach Roy Williams might not be as animated as usual during tonight's Carrier Classic.

The coach told ESPN.com's Andy Katz that he started suffering symptoms yesterday, and was concerned about it today. He will coach against Michigan State, however, on the flight deck of the USS Carl Vinson. Tip-off is roughly 7 p.m. EST.

Williams has suffered vertigo in the past, but it hasn't been a concern lately.
