"On Friday, Bengals running back Cedric Benson presented to an outside arbitrator a grievance regarding his one-game suspension (plus one-game fine) for violation of the league's personal conduct policy during the lockout. Per a source with knowledge of the situation, the grievance has been rejected.
Benson didn't expect to play on Sunday, even if he prevailed. It's somewhat surprising that the ruling came as quickly as it did."
