My mother has DirecTV & it's now updated to say UT-Kentucky game on SEC Network which is channel 611. You should probably be the same channel.
What does it say is on at noon Saturday on channel 611 right now? My mother's just updated today. It didn't haven the game listed before today.
Edit: Just looked back a few posts & you said you had Dish instead of DirecTV so what I said wouldn't pertain to you. Still, whatever channel the SEC Network is on is where to look even on Dish. You're saying it has the Vandy-Mizzou game listed still for SEC Network on Dish too?
