The Indianapolis Colts will be missing three defensive starters Sunday against Oakland.

Team spokesman Craig Kelley says cornerback Kelvin Hayden, linebacker Clint Session, defensive tackle Daniel Muir and backup running back Mike Hart did not make the trip.

Session hasn't played since Nov. 1 because of a broken right forearm and dislocated right elbow. Hayden will miss his third straight game with a neck injury. Muir is sitting out with a chest injury, meaning the Colts will be without their best run-stuffer against Darren McFadden and Michael Bush.

The good news is two-time 1,000-yard runner Joseph Addai made the trip and is likely to play for the first time since hurting a nerve in his left shoulder Oct. 17.
