My service provider was not one of the 5 major ones listed so I researched how I might be able to watch the game today. This is what I found out and it appears I will be able to watch the game but won't know until I try it. Hope it works.
To see if your service provider is on the list to permit remote access go to:http://espn.go.com/watchespn/affList
If so, then go to watchespn.com. Make sure you are on the full web site and not the app.
Click on "Remote Access" and on the next screen go to the last line for those who do not have a free account with watchespn.com and click on the blank. Fill out the information to get free login information. When you return to watchespn.com then login if necessary. Select "Remote Access" again....if it ask you to sync your account then do so. Hopefully you should then be able to watch the game.
Once logged in you should be able to view the schedule for espn3 but make sure the right date is selected.
I don't know if this is what is called backdooring espn3 or not and I won't know for sure if this will work until later. I live in Kentucky and my provider is on the list so I am hoping. If I have any problems I'll give them a call so you can always call your provider and ask I guess.
Hope this helps those in similar situation.
