The game between the Tampa Bay Buccaneers and San Diego Chargers was blacked out, and that means that a lot of people in the local market missed the game. If you're inside the Tampa TV market, you should be able to watch the game by following this link.
The game should be available for a few days, although it won't be operational during Monday Night Football. It's also possible that your IP address doesn't show up as being inside the blackout zone, even though you are - you could contact the helpdesk at the link.
Finally, if you're outside the blacked out area but still want to catch the game, you could pay for the Game Rewind service and get access to the game every week.
