Bradley Fletcher is day-to-day with a concussion, leaving the Eagles a little more vulnerable at cornerback as they gear up for quarterback Philip Rivers and the Chargers.

Brandon Boykin.

Brandon Boykin is the next man up per defensive coordinator Billy Davis. Brandon Hughes might also be active although he's coming off a broken hand that’s basically sidelined him for close to a month.

Rookie seventh-round pick Jordan Poyer played in the first game, but his 17 snaps didn't go real well.

Then there's Shaun Prater, claimed after the big cuts. He was deactivated the first game.

“As soon as the system is picked up well and we see what we have,” Davis said, “then he can be part of it.”

Free safety Patrick Chung, who played all 75 snaps on defense in the opener, can also play cornerback.
