‘Linebacker Junior Seau (groin) worked on Thursday; Sam Rogers (thumb) didn’t. But coach Mike Riley said Rogers is more certain to play Sunday against the Bills than Seau. "He’s not full speed, so we are going to reserve judgment,” Riley said of Seau. "But it is encouraging that he worked a little bit today." Said Seau: "I practiced at a controlled pace.” Riley said Rogers will play with a cast on his dislocated thumb. If Seau can’t go, Gerald Dixon would move from the strong side to Seau’s weakside position, with Rogers taking Dixon’s spot.’
