Of the 15 teams I have listed in Friday's Bubble Watch update, 13 are in action on Saturday. Plus, there are a few other games on the schedule that could result in teams falling down to this group.
Be sure to check out my new pre-weekend bracket, which will be updated again on Monday.

Last Four In
All four teams are in action this afternoon, with three involved in favorable matchups.
Rhode Island at St. Bonaventure, 2 p.m. ET (no TV): The Rams visit head coach Jim Baron's alma mater (and former employer) looking for their second straight win. Rhody can't get caught looking ahead to Wednesday's crucial home game against Charlotte.
Tulane at UAB, 2 p.m. ET (no TV): The Green Wave own only two Conference USA wins this season, both coming over Rice. Playing at Bartow Arena, the Blazers should be able to win their fourth straight.
No. 1 Kansas at Oklahoma State, 4 p.m. ET (CBS): The Cowboys face the biggest challenge of the Last Four In, but a little more than two years ago, they were able to stun the Jayhawks, a team en route to a National Championship.
Charlotte at George Washington, 6 p.m. ET (MASN): The 49ers won a close home game against the Colonials on February 3. They go for the sweep this evening, and look to ride a two-game win streak heading into Wednesday's clash in Kingston.
First Four Out
San Diego State is off this weekend, meaning they can't make a case to jump back in until their closing stretch against Colorado State and Air Force next week. The other three teams all face stiff tests.
Notre Dame at No. 11 Georgetown, 12 p.m. ET (CBS Regional): The Irish look to follow up on Wednesday's big home win over Pitt with an even bigger road win, but they'll probably have to do it without Luke Harangody.
Cincinnati at No. 8 West Virginia, 2 p.m. ET (Big East Network/Full Court): The Bearcats also hit the road looking for a marquee win. Mick Cronin's team hasn't beaten a team that's safely in since Maui.
Arizona State at California, 3 p.m. ET (FSN/Comcast SportsNet): The Golden Bears can all but wrap up the Pac-10 regular season crown, and seriously boost their at-large chances in case they fail to win the conference tournament in Los Angeles in two weeks. The Sun Devils can boost their own case for an at-large by grabbing a second Top 50 RPI win.
Next Four Out
All of these teams are in action, but none faces an opponent who can really boost the resume.
Mississippi at Alabama, 2 p.m. ET (ESPN2): The Rebels look to replicate the effort of their in-state rivals, who beat the Tide Wednesday night.
Mississippi State at South Carolina, 6 p.m. ET (ESPN): It's the first of two road games for the Bulldogs before a key home clash against Tennessee in seven days' time.
Massachusetts at Dayton, 7 p.m. ET (WHIO/CSN Regional): The Flyers will hope to score a few more points than they did against Temple Wednesday night.
Washington at Washington State, 10 p.m. ET (FSN Northwest/FCS Pacific): The Cougars would love nothing more than to knock the Huskies down to .500 in the Pac-10, which would probably end their at-large hopes, as next week's road trip to Oregon and Oregon State won't provide a resume boost.
On The Fringe
Of this group, two teams are in action Saturday. Seton Hall hosts Marquette on Sunday.
Providence at South Florida, 7 p.m. ET (ESPN360): The Bulls look to sweep the Friars and keep hopes of a .500 Big East record alive.
Minnesota at Illinois, 8 p.m. ET (Big Ten Network): The Golden Gophers missed their chance against Purdue Wednesday night. With games against Michigan and Iowa coming up, this is their last opportunity before the Big Ten Tournament. The Illini on the other hand need this one as well, considering they visit Ohio State and host Wisconsin to close.
Other Games Of Bubble Note
Key CAA and ACC battles, and a tricky road game for the last SEC team in, are also on the Saturday schedule.
VCU at Old Dominion, 4 p.m. ET (CSN Regional): The Monarchs look to avenge a 70-58 road loss to the Rams and sew up the CAA regular season crown.
Maryland at Virginia Tech, 4 p.m. 6:30 p.m. ET (Raycom Regional/Full Court: Check Local Listings): The Terps can lock up a big with a win in Blacksburg, while the Hokies really need a win after Wednesday's embarrassing loss to Boston College. NOTE: This one has been delayed by a water main break. Local affiliates will determine TV coverage.
Florida at Georgia, 4 p.m. ET (SEC Network/Full Court): The Bulldogs, who fell apart in the final moments of regulation at Vanderbilt on Thursday, host a Gator team who can't get caught looking ahead to a tough closing week (Vanderbilt, at Kentucky).
