An ankle injury prevented Bills starter Ryan Fitzpatrick from practicing Wednesday, opening the possibility for Brian Brohm to make his NFL debut at Atlanta this weekend. Interim head coach Perry Fewell declined to rule out Fitzpatrick, saying the quarterback was feeling better after he was hurt in a 17-10 loss against New England last weekend. Fewell did rule out Trent Edwards, after the backup also hurt his ankle last weekend. Brohm spent a majority of practice working with the first-team offense, ahead of Gibran Hamdan, who re-signed with Buffalo on Tuesday.
