NCAA Tournament 2015: TV schedule and live streaming for Sunday's Elite 8 action

Kentucky and Wisconsin are booked in the Final Four. On Sunday, we'll find out who joins them.

Louisville and Michigan State kick things off in a rare 4 vs. 7 Elite Eight matchup. I don't think anybody's that shocked that the Spartans are in this game -- it's just Tom Izzo doing Tom Izzo things in March -- but there were plenty of people who didn't have Louisville making it this far. A late slide in the regular season had most folks picking the Cardinals as a one-and-done, but they've become a completely different team in the tournament.

After that, Duke will be trying to avoid another early March exit when they take on Gonzaga. There's no question that the Blue Devils have the more talented starting five, but the Zags' depth could give them a shot at the upset.

At least that's what Gonzaga blog The Slipper Still Fits is hoping.

[Jahlil Okafor, Justise Winslow, Tyus Jones and Quinn Cook] account for virtually all of Duke's offensive output so the Bulldogs definitely have more offensive contributors. This could particularly help in the post as Kyle Wiltjer, Przemek Karnowski and Domantas Sabonis are playing at an exceptionally high level and could put a lot of pressure on Okafor.
