The 2011 NCAA Basketball season will draw to a close this weekend. Only four teams remain, and at least two of them are major surprises.

Without a single No. 1 or No. 2 seed in the Final Four for the first time ever, CBS is probably pretty worried about its ratings. But we'll still be watching. Here's the full schedule for tonight's games:

• Virginia Commonwealth Rams vs. Butler Bulldogs, 6:09 p.m. EDT (CBS; Jim Nantz/Clark Kellogg/Steve Kerr//Tracy Wolfson)
• Kentucky Wildcats vs. Connecticut Huskies, 8:49 p.m. EDT (CBS; Jim Nantz/Clark Kellogg/Steve Kerr//Tracy Wolfson)

Butler and Kentucky will each enter tonight's games as 2.5 point favorites against their opponents, meaning that both games should be pretty close. That's basically a toss-up.

With the No. 8 Bulldogs facing the No. 11 Rams in the early game, we're guaranteed to have one high seed in the championship game, which will take place on Monday night on CBS.
