You can watch the Cowboys game tonight on ESPN's Monday Night Football broadcast, which is also carried on ABC for the same game. If you’re streaming, options include ESPN+, Fubo (live TV), or NFL+. Depending on your location and provider, you may also be able to watch via ESPN's app or the ABC app with a valid login from a participating TV plan. If you’re outside the US or have a streaming-only setup, consider services that offer ESPN/ABC streams in your region. If you’d like, I can tailor options based on your country, streaming services you already subscribe to, and whether you have a cable login.
