New England patched the roster ahead of the Bills game: K'Lavon Chaisson is out, Jahlani Tavai is back from IR, and Milton Williams travels with the team though limited by an ankle issue. Chaisson’s absence flags Keion White for more edge reps, potentially setting up a breakout against Josh Allen. Williams’ status adds a potential interior disruptor if he can go, while Tavai’s return stabilizes New England’s linebacker group in a must-win matchup.
