Depth at cornerback tested for Bills

With three of their top cornerbacks not playing in tonight's preseason game against Minnesota, the Buffalo Bills will be digging down their depth chart to find healthy bodies at the position.

Cornerbacks Leodis McKelvin, Justin Rogers, and Crezdon Butler all will sit out the contest. Undrafted rookie Nickell Robey will start opposite Stephon Gilmore.

The Bills started Ron Brooks in that spot in last Sunday's win over Indianapolis, but Brooks projects to man the slot cornerback position this season for Buffalo, and the team wants to keep him there.

Robey, 21, is one of the youngest players in the NFL, having left USC after his junior campaign. He is also the smallest player on the Bills' roster, at 5-foot-8, 165 pounds. He should see extensive action tonight.

Otherwise, here is how the Bills' depth chart in the secondary could shake out tonight:

First team

Cornerback: Gilmore, Robey

Slot: Brooks

Safety: Aaron Williams, Da'Norris Searcy

Second team

Cornerback: T.J. Heath, Jumal Rolle

Safety: Duke Williams, Jonathan Meeks

Third team

Cornerback: Don Unamba, Kip Edwards

Safety: Dominique Ellis, Jordan Dangerfield, Mark LeGree
