If you have any television provider that has SEC Network, you should be able to watch the game. For example, I have YouTube TV. To watch tonight's game, I'll do the following:
1. Click on the ESPN app on my smart TV.
2. Scroll down until I see the category channels.
3. Scroll over to SEC+ (NOT ESPN+).
4. Click it.
5. Then click on the game.
6. If you're given a code, you'll need to enter it via espn.com/activate and login to your TV provider (Dish, YouTube TV, Spectrum, Direct TV, etc.).
7. After that, you should be good to go.
