McCardell to fill in for Moss?

Keenan McCardell appears close to signing with the Redskins. He could be practicing with the team as soon as Monday, according to the Washington Post. It's possible this means that Santana Moss could miss some games due to his groin injury, or else the Redskins are just trying to add some veteran depth for the long haul. It will be interesting to see if Moss is able to practice on Wednesday.
