Edmond police spokeswoman Jennifer Monroe says Clark was a passenger in a vehicle that was pulled over for a seatbelt violation. Police discovered marijuana in the vehicle and arrested Clark and the driver on possession of marijuana complaints.
Clark, a backup point guard, is averaging 7.0 points for the sixth-ranked Cowboys.
The school didn't immediately comment on Clark's arrest.
