Here's what you need to know for Tuesday, Feb. 6.

Game of the night

Xavier at Butler, 6:30 p.m. ET, FS1: The Bulldogs have already knocked off No. 1 Villanova at home. If Butler gets second-place Xavier, too, then the Bulldogs will be working on a higher NCAA tournament seed as well as one in the Big East tournament. Xavier has flirted with some fire lately against St. John’s and Georgetown but has survived.

Also in the Big East, Georgetown at Providence (8:30 p.m. ET, FS1) is a game the Friars need to win to keep pace in a four-team battle for third.

Michigan State at Iowa, 9 p.m. ET, ESPN: Will the Spartans get off to a fast start on the road against a lesser opponent ahead of a big game against Purdue on Saturday?
