According to Adam Caplan, the Eagles will work out veteran WR Kelley Washington this week. Washington was with the Eagles in training camp, but was cut after the preseason.
The Eagles interest in bringing back Washington could be do part to the injury to Riley Cooper, but also due to the fact that Washington is known as an excellent special teams player. The Eagles coverage units struggled again on Sunday night and they could be looking to Washington to help shore up that unit.
If Washington was signed, my guess is that it would be at Chad Hall's spot on the roster he'd be taking.
