Hairston and McDonald are both out because of issues that are possibly NCAA-related.
Hairston, a junior, had multiple run-ins with law enforcement during the offseason and was also caught driving a rental vehicle linked to an ex-convict with questionable motives. McDonald's issues are apparently rooted in the fact that a company called Iceberg Guards advertised McDonald, a senior, as a user of its mouth guards, which seemingly violates NCAA bylaws. There's no timetable for a resolution in either case.
UNC is ranked 12th in the preseason AP poll.
The Tar Heels' first game is Friday against Oakland.
