Linebacker London Fletcher, cornerback DeAngelo Hall and safety Oshiomogho Atogwe started Sunday's game vs. Buffalo.
Due to injuries, each had been listed as questionable heading into the game.
Fletcher continued his consecutive starts streak – he has now started 170 games, second-most among active NFL players behind Tampa Bay cornerback Ronde Barber.
Fletcher has also played in 215 consecutive games, which is tied with Barber for most in the league.
Fletcher missed practice time early last week due to a hamstring injury, but he was able to increase his work later in the season.
His presence in the lineup was thought to be a key as the Redskins aimed to slow Bills running back Fred Jackson.
Hall was slowed by a hip injury and Atogwe had a knee injury. Like Fletcher, they both increased their practice workload late last week.
