Collins, 24, was charged last Thursday during a traffic stop in Fauquier County in northern Virginia's horse country, state police said.
A state police spokeswoman said Monday that Collins was on Route 29 when his vehicle was stopped for an illegal window tint. A trooper detected the odor of marijuana coming from Collins' vehicle and the spokesman said Collins agreed to allow the trooper to search his 2011 Dodge.
State police said a small amount of marijuana was found. Collins also was charged with a window tint violation.
Collins listed his address as Charlottesville, where he played for the University of Virginia. A listing under his name could not be found.
