What happened: The Buffalo Bills announced their inactive list for Sunday against the Baltimore Ravens, ruling out tackle Spencer Brown and defensive lineman Greg Gaines. Brown was sidelined with a back injury, while a calf issue kept Gaines out of action. Buffalo also designated Skyler Bell, Ar'Maj Reed-Adams, Mike Danna, Dee Alford, and Jalon Kilgore as inactive.

Why it matters: With Brown unavailable, Tylan Grable is in line to start at tackle alongside rookie Jude Bowry, who is active for the first time this season. The Bills received a boost with Ed Oliver back on the defensive interior and DJ Moore active at receiver. Buffalo seeks to protect its standing in the AFC East race while Baltimore enters fourth in the AFC North.

What to watch: Kickoff is scheduled for 1:00 PM ET as Buffalo manages its reshuffled offensive line.
