Gonzalez (shoulder) did not practice Wednesday.
Gonzalez likely picked up the injury during the Patriots' 35-6 loss to the Jaguars in Week 3, when he recorded two solo tackles and a pass defense while failing to play every single defensive snap for the first time this season. He'll have two more chances to return to practice this week, but if he cannot play against the Bills this Sunday, then Charles Wood figures to be the top candidate to start at outside cornerback opposite Carlton Davis.
