Keyaron Fox, who has been backing up Kendrell Bell at the right side position, will join Bell on the sideline, coach Dick Vermeil said Thursday. Fox has been bothered by a hamstring pull. Bell, who has a recurring shoulder problem, is being held out of contact work for at least another week.

The Chiefs also won’t have blocking tight end Jason Dunn available for a second straight game. Pro Bowl tight end Tony Gonzalez may play on a limited basis with a protective covering over his fractured pinky finger.
