KANSAS CITY, Mo. -- The Kansas City Chiefs made an interesting choice by releasing a reserve nose tackle, Cam Thomas, to clear roster room for newly signed cornerback Darrelle Revis.

They're down to five players on the defensive line, which shouldn't be a problem considering the Chiefs use defensive fronts that usually consist of two or three down linemen.

The Chiefs now have six cornerbacks and 11 players in the secondary. That's more than they've carried at those positions all season and even though they like to play defenses that feature a lot of defensive backs, somebody is going to be sitting on game day.

They've used their nickel defense with five defensive backs 336 times, which is fifth highest in the league. They've gone to the dime with six defensive backs 123 times, seventh most in the league. They've even used at least eight defensive backs on six snaps, which is third highest in the league.

But safeties Ron Parker and Daniel Sorensen and cornerback Marcus Peters are constants. They rarely leave the field when the Chiefs are on defense, so playing time will dwindle for at least some of their cornerbacks, where the Chiefs have a crowd.

Peters will of course remain a starter. The plan is for Revis to join him as soon as possible in the lineup, though that's unlikely for Sunday's game against the Buffalo Bills at Arrowhead Stadium.

If that happens eventually, Steven Nelson would become the nickelback. Unless there's an injury to one of those three players, Phillip Gaines, Terrance Mitchell and Kenneth Acker are battling for leftover playing time, which won't be much.

Each has been pulled from the lineup at various times this season as the Chiefs searched for some consistency at an important position. Their inability to adequately handle the position led the Chiefs to sign Revis.

Gaines took his turn in last week's loss against the New York Giants and was beaten for a long gain on the game's most important play. Giants wide receiver Roger Lewis beat Gaines for a 34-yard gain on a fourth-down play in overtime. The pass gave the Giants the ball at the Kansas City 2 and set up the winning field goal.

But the Chiefs kept them all. They could certainly make another roster move soon involving one of them, and perhaps they're just waiting for Revis to get up to speed before they do.
