The Redskins' defense has mostly avoided season-ending injuries so far, unlike the offense, but several key players are still banged up heading into Week 8.

Linebacker London Fletcher, cornerback DeAngelo Hall and safety Oshiomogho Atogwe are all listed as questionable for Sunday's game against the Buffalo Bills in Toronto.

Fletcher suffered a hamstring injury in last week's game at Carolina. The injury improved through the course of the week and he was limited in practice on Friday.

"Unless there is a setback, I think he should be able to go," head coach Mike Shanahan said.

Hall and Atogwe were also limited in practice Friday. Hall has a hip injury and Atogwe has a knee injury.

Reserve cornerback Phillip Buchanon is also questionable for the game with neck and knee injuries.

If Hall is unable to play, then Kevin Barnes would likely draw the start.

Atogwe sat out last week's game vs. Carolina due to his knee injury. He would be replaced by Reed Doughty at free safety if he is unable to play.
