What happened: Pryor brings 40 career starts with guard-tackle flexibility from Arizona's practice squad. Thursday lists Jeremy Springer at 12:45 p.m. and Josh McDaniels at 1:05 p.m., with practice at 2:10 p.m. followed by Zak Kuhr.

Why it matters: New England sits 1-2 entering Week 4, increasing the need for experienced offensive line depth. Buffalo averages 5.2 yards per carry, tied for second in the NFL, framing a physical week in the trenches.

What to watch: Watch whether the signing becomes official and if Pryor is available for practice ahead of the Buffalo game.
