The Kansas City Chiefs' secondary, already missing Pro Bowl safety Eric Berry, has been further depleted with backup safety Jon McGraw and cornerback Javier Arenas inactive against the Miami Dolphins.
McGraw hurt his shoulder in last week's 23-20 overtime win over San Diego. Arenas, who has emerged as the Chiefs' best return man, had been listed as questionable with an ankle injury.
Dolphins cornerback Vontae Davis is inactive after the team announced he would be out for ''non-injury reasons.'' Davis has been bothered by a hamstring, and was also reportedly involved in an altercation with wide receiver Brandon Marshall in practice.
Running back Steve Slaton and defensive end Phillip Merlin are among the other players inactive for Miami.
