Coach Roy Williams broke his silence earlier this week regarding North Carolina shooting guard P.J. Hairston’s arrest, despite originally pledging to withhold comment until all the facts were gathered.

In a statement released Monday, Williams said he had spoken to Hairston about serious mistakes he had made, and he promised “serious consequences.”

“Certainly the idea of suspending P.J. has been discussed,” Williams said.

“However, he is not currently enrolled in summer school, is not practicing with the team and we have no games until November.”

At a Durham license check in early June, Hairston was arrested and charged with driving without a license and possession of marijuana.
