According to a report from the Twitter feed of ProFootballTalk.com, Cincinnati Bengals running back Cedric Benson will miss Sunday's game at the Seattle Seahawks after his one-game suspension was upheld by the league. According to @ProFootballTalk:
Per league source, RB Cedric Benson's non-injury grievance has been rejected. Suspension stands.
Benson was suspended three games for violating the NFL's personal conduct policy, but the suspension was reduced to single game on appeal. The non-injury grievance represented Benson's last effort to further reduce the suspension.
