The Le'Veon Bell and LeGarrette Blount pairing had been an ideal one -- until Wednesday afternoon.

The Pittsburgh Steelers running backs will be charged with marijuana possession following a traffic stop the day the Steelers flew to Philadelphia for their third preseason game.

Ross Township detective Brian Kohlhepp said traffic officer Sean Stafiej pulled over a Camaro operated by Bell around 1:30 p.m. after Stafiej, who was on a motorcycle, noticed a strong odor of marijuana coming from the vehicle. Stafiej found a 20-gram bag of marijuana inside the car. Bell, Blount and a female passenger all claimed ownership of the marijuana, according to police.

Bell, 22, was taken to a hospital to have blood drawn and is expected to be charged with driving under the influence of marijuana.

Bell, Blount and the female passenger are expected to receive notice of formal charges through the mail, said Kohlhepp. The possession and DUI charges are both misdemeanors.

The incident happened less than two hours before the Steelers flew to Philadelphia for a preseason game Thursday night against the Eagles.

"We are aware of the reports and still gathering information," Steelers spokesman Burt Lauten said. "We will have no further comment at this time."

The team could hold both out of the Steelers' game Thursday night against the Eagles, and the NFL is expected to review the incident. Bell didn't fly with the Steelers to Philadelphia, according to multiple reports, but later made his own way to the city to rejoin the team, a league source told ESPN's Sal Paolantonio. Blount is with the team, according to ESPN's Ed Werder and multiple reports.
