Eagles cornerback Bradley Fletcher did not practice Wednesday because of a concussion while cornerback Brandon Hughes returned to practice in his recovery from a broken hand.

Fletcher is "day-to-day" defensive coordinator Bill Davis said. He is a starting cornerback so his absence could force the Eagles to make major adjustments on defense. Recovery from a concussion varies depending on the player and the severity so it is unknown whether Fletcher will play Sunday against the San Diego Chargers.

The Eagles will have a few contingencies if Fletcher does not play. The first one would be moving Brandon Boykin to the outside from the slot Davis said. Boykin a second-year player had an interception against the Redskins.

He is listed at 5-foot-10 although he measured one inch shorter at the 2012 combine. His height is why he is viewed primarily as a slot cornerback but he insists he can play on the outside.

"Regardless of what your height is the main objective is you have to go out and get it done" Boykin said. "Every week I'm going to face people who are taller than me. . . . I'm ready for it and I demand greatness from myself when the ball's in the air."

Potential options in the slot if Boykin moves to the outside would be Hughes Shaun Prater and Jordan Poyer. The Eagles also could play Patrick Chung in the slot and use Earl Wolff at safety.
