Direct answer: For watching the Chiefs vs Bills game, the matchup is typically broadcast on CBS in the United States, with live streaming available through NFL+ and CBS streaming platforms, plus regional or local options depending on your location. The game time and channel can vary by week, but recent schedules have the Bills hosting the Chiefs at 4:25 PM ET. If you’re outside the U.S., check your local sports networks or streaming services that carry NFL games in your region. Details and options to watch:

• TV broadcast: CBS in most U.S. markets for this Week 9 matchup against the Chiefs.
• Live streaming: NFL+ (with in-market streams depending on rights) and CBS streaming platforms (through a cable authenticated login or app).
• Radio and other listens: Local Chiefs or Bills radio networks; Chiefs Rewind and Field Pass on team channels.
• International viewers: Check regional broadcasters or streaming services like DAZN in certain countries, or local equivalents offering NFL games on Sundays.

Tips to ensure access:

• Confirm your local CBS affiliate and kickoff time in your time zone, as schedules can shift.
• If you have a streaming service that carries CBS (such as a duing package with NFL on CBS), use that to stream the game.
• If you already subscribe to NFL+ or parameter-specific services, verify availability of in-market or national streams for this game.

If you’d like, specify your country or streaming services you have access to, and the exact kickoff time in your time zone, and the answer can be tailored with precise channel numbers and streaming steps.
