Police have filed marijuana possession charges against Pittsburgh Steelers running backs Le'Veon Bell and LeGarrette Blount following a traffic stop.

Police in the Pittsburgh suburb of Ross Township say a motorcycle officer pulled over Bell's Chevrolet Camaro when he smelled marijuana coming from it around 1:30 p.m. Wednesday.

Detective Brian Kohlhepp has said the players and a woman in the car, 21-year-old Mercedes Dollson, of Elk Grove, California, were polite and cooperative.

Kohlhepp says all three acknowledge the three-quarter-ounce of marijuana found in the car belonged to them.

Online court records show all three have been charged with marijuana possession. Bell is also charged with driving under the influence because, in Pennsylvania, driving while using any amount of an illegal drug is a crime.

The court records don't list defense attorneys.
