Falcons vs. Redskins: Aldrick Robinson passes concussion test, participates fully in practice

Washington Redskins rookie wide receiver Aldrick Robinson fully participated in practice on Thursday. Robinson passed a concussion test, which was necessary after an injury suffered in a pregame collision with teammate Brandon Meriweather on Sunday. Robinson has caught seven passes for 103 yards and a touchdown in three games this season.

Cornerback Cedric Griffin did not practice as he recovers from a hamstring injury that forced him to miss Sunday's game against the Buccaneers, according to the team's official twitter account. Running back Evan Royster was limited with a knee injury, while Brandon Banks was also limited with a sore hip.

Redskins left tackle Trent Williams fully participated in practice. The third-year veteran has been battling a knee injury, but has started all four games for the Redskins.

The Redskins would like to be at full-strength, as they host the undefeated Atlanta Falcons on Sunday at FedEx Field. Washington sits at 2-2 and wants to keep pace with the division-leading Eagles.
