Chiefs' defensive depth will be tested now

KANSAS CITY, Mo. -- Just as they had reason to feel good about where their season is headed, the Kansas City Chiefs lost a pair of defensive starters in lineman Allen Bailey (shoulder) and inside linebacker Justin March (hand).

The Chiefs have already played most of the last two games without starting cornerback Phillip Gaines, who was not among the flurry of roster moves they made on Tuesday. But the Chiefs promoted a corner, Terrance Mitchell, off the practice squad, so they feel they could need another body there for Sunday's game against the New Orleans Saints.

The Chiefs can survive the loss of Bailey. He will be replaced by rookie Chris Jones, their second-round draft pick. Jones played well in replacing Bailey after he left with the injury on Sunday against the Raiders. The Chiefs also added a couple of bodies to their potential defensive line rotation by signing veteran Kendall Reyes, a former starter with the Chargers, and elevating Rakeem Nunez-Roches from the practice squad.

The Chiefs have no such obvious candidate to replace March. He himself was a replacement for the original starter, Josh Mauga. His season ended with an injury in training camp.

The Chiefs have some choices to replace March and the most intriguing is veteran Sio Moore. The Chiefs signed Moore two weeks ago and he hasn't played in a game for them yet. They were practicing Moore as an outside linebacker but the move with March may force them to change plans.

Another possibility is Sam Barrington, who was signed at the end of training camp. He is a former starter with the Packers.

Gaines tore his ACL last season but returned for the start of this year. He injured the knee in a recent practice and sat out a game against the Pittsburgh Steelers.

Gaines returned to start in Oakland but left in the second quarter after having a relapse and didn't return.

But the Chiefs, after adding Mitchell, have six cornerbacks on their roster, so they evidently believe they'll need the depth against the Saints, and perhaps beyond.
