Dunn, a 19-year-old incoming freshman who was a star back at Canton's GlenOak High School, was cited early Sunday during a routine traffic stop. Police found a small amount of marijuana and a marijuana pipe in the car, which belonged to his mother. Dunn denied that the marijuana or drug paraphernalia belonged to him.
His arraignment is set for Wednesday. The Buckeyes open practice this Friday with Dunn expected to vie for playing time.
The disorderly conduct charge is a minor misdemeanor. The police report says he nearly hit a patrol car.
