Brandon Meriweather practices

ASHBURN, Va. -- Safety Brandon Meriweather, who missed the Washington Redskins' opener with a groin injury, practiced in full for the first time since before the preseason finale. That’s good news for a team in need of more help in the secondary.

Without Meriweather, the Redskins were forced to start corner E.J. Biggers at strong safety against the Philadelphia Eagles. And with a high-powered offense up next in the Green Bay Packers, the Redskins could use a strong cover safety.

The problem is, nobody really knows what Meriweather will do, because it’s been nearly a year since he played in a game, and he was only able to play one game in the preseason. When healthy, he could make a difference in the secondary. The problem has been keeping him healthy.

“Hopefully it changes,” Redskins coach Mike Shanahan said. “He’s been a big playmaker in the limited time he has played over the last year. I think everybody knows what he’s done and hopefully he can keep playing at that level.”

Meanwhile, corner David Amerson (back) and defensive lineman Chris Baker (illness) were limited in practice. We did not have a chance to ask Amerson or Shanahan about his back (the injury report was not available until after the press conferences). So we’ll find out more about that Thursday.
