Here's what you need to know in college hoops for Wednesday, March 1.

Happy March! It's finally here! We've got conference tournaments, Naismith semifinalists and the NCAA Bracket Challenge. Let's get to it:

In case you missed it

• No. 9 Kentucky had an exciting start to Senior Night. Senior forward Derek Willis proposed to his girlfriend before the game. The actual game, though, started out much worse for the Wildcats, with unranked Vanderbilt climbing to a 19-point lead. UK coach John Calipari has never lost on a Senior Night, and so the Wildcats slowly clawed back, riding a 7-0 run to take the lead and finally winning, 73-67.

• Grayson Allen was back on the court for No. 17 Duke as it took on No. 15 Florida State (though he didn't start). The Blue Devils had no problem with the Seminoles, cruising to a 19-point second-half lead, then holding off a late rally to win 75-70. The loss knocked Florida State out of contention for the ACC regular-season title.

• Leading by 10 points with four minutes remaining, No. 24 Iowa State saw Oklahoma State claw back to within a single possession less than two minutes later but held on to inch closer to a second-place finish in Big 12 play. The Cyclones won 86-83.

• Eastern Michigan's Ray Lee dropped 50 as the Eagles beat Central Michigan.

What to watch today

No. 12 Florida (23-6) vs. Arkansas (22-7)  (7 ET, ESPN2). The Gators will close out their regular season at home with a matchup against the Razorbacks. Arkansas (22-7, 11-5 SEC) will look to extend its winning streak to six and set a program record with a seventh SEC road win of the season. The Gators (23-6, 13-3) aim to rebound from a loss to Kentucky. Florida is 8-1 at home during conference play.

No. 8 Louisville (23-6) vs. Wake Forest (16-12) (9 ET, ACCN). The Cardinals will try for a fifth win in six games when they visit a Wake Forest squad in desperate need of a resume-boosting victory. The Demon Deacons, who have not made the NCAA tournament since 2010, narrowly avoided a devastating loss to Pittsburgh on Wednesday to snap a two-game skid.
