Bracketology Bubble Watch: Wisconsin facing Purdue highlights Tuesday's games involving teams near cut line

The action on the bubble picks up on Tuesday with two double-bubble games. One team each in the last four in and first four out are in action on the road, and two other teams just barely out of those groups play as well.

There was only one bubble team in action Monday and here's what happened and why it's important:

Xavier beat host St. John's 77-74: The Musketeers' fourth victory in its last five games has them now 3-8 vs Quadrant 1 opponents. That's not a great record against that group, but the they are an even 9-9 vs Q1-2. Xavier, a No. 8 seed in the latest bracket, gets Villanova at home Saturday and a shot at its second best win of the season.

Here are Tuesday's games involving bubble teams. All times are ET.
