The five-seed San Diego State Aztecs are through to their first Final Four in school history after grinding out a low-scoring 57-56 win against the six-seed Creighton Bluejays in Sunday's Elite 8 action.

With their seasons on the line, the two sides combined to shoot a dismal five-of-30 (16.6 per cent) from three-point range, but there were no such struggles for Aztecs junior guard Lamont Butler.

Butler posted a game-high 18 points on eight-of-11 shooting, nailing both of his three-point attempts, while only committing one turnover in his 30 minutes.

Seven-foot-one Creighton center Ryan Kalkbrenner continued his strong NCAA Tournament with a team-high 17 points (eight-of-17 shooting), six rebounds and two blocks.

It was not without controversy though, as after Bluejays senior transfer Baylor Scheierman tied the game with 32 seconds remaining, San Diego State's Darrion Trammell was fouled on the potential game-winning floater with 1.2 seconds on the clock.

Creighton's players and coaches were apoplectic at the call, which was borderline, and after Trammell missed the first free throw, he drained the second to secure the one-point victory.

They will face this year's most unlikely Final Four participants next, with Florida Atlantic waiting in the wings after having never won a single game in the NCAA Tournament prior to this season.

Meanwhile, the five-seed Miami Hurricanes also booked their ticket to the first Final Four in school history after an 88-81 triumph over two-seed Texas.

The Hurricanes were coming off their first ever Elite 8 appearance in 2022, and they have gone even further this time around thanks in large part to the spectacular showing from senior wing Jordan Miller.

Miller scored a game-high 27 points – his highest total since November 2020 – while shooting a perfect seven-of-seven from the field and 13-of-13 from the free throw line.

All five of Miami's starters scored at least 11 points each, and they did it in old-school fashion, shooting 59 per cent from the field while only attempting eight three-pointers as a team.

The Hurricanes will meet the Connecticut Huskies in the Final Four, who are the only team seeded fourth or lower in NCAA Tournament history to win four games in a row by double-digits.

Top overall seed Alabama were ousted from the NCAA tournament Sweet 16 after an upset 71-64 loss to San Diego State on Friday.

The Crimson Tide were well below their best in a sloppy performance with 14 turnovers, shooting three-of-27 from beyond the arc.

SDSU's Darrion Trammell scored 21 points as San Diego progressed to the Elite Eight for the first time.

Trammell led the way offensively for the Aztecs, while Nathan Mensah had eight rebounds and five blocks, while Lamont Butler had three steals, four rebounds and four assists.

For Alabama, top-five NBA Draft prospect  Brandon Miller scored nine points with 11 rebounds but committed six turnovers and shot three-of-19 from the field, including one-of-10 from three-point range.

Crimson Tide guard Mark Sears scored 16 points with 10 rebounds but shot none-of-five from beyond the arc.

"Everybody is really disappointed in the loss," Alabama coach Nate Oats said. "It ended too soon."

Midwest regional top seed Houston were also eliminated in the Sweet 16 on Friday after losing 89-75 to Miami.

Hurricanes guard Nijel Pack led the way with 26 points including seven-of-10 three-pointers as Miami made 11 of their first 22 attempts from beyond the arc.

Miami will take on Midwest second seed Texas in the Elite Eight after the Longhorns won ___ over the Xavier Musketeers, with Tyrese Hunter scoring a team-high __ points with __-of-__ three-pointers.

South regional six seed Creighton defeated Princeton 86-75 to set up a Elite Eight meeting with SDSU, after Ryan Kalkbrenner and Baylor Scheierman scored 22 and 21 points respectively.

Hall of Fame Michigan State head coach Tom Izzo earned his 15th trip to the Sweet 16 after eliminating two-seed Marquette 69-60 in Sunday's second round of the NCAA Tournament.

The Spartans rode a 23-point performance from senior point guard Tyson Walker, while Joey Hauser – brother of Boston Celtics wing Sam Hauser – collected 14 points and 10 rebounds.

As well as pulling into a tie for the sixth-most Sweet 16 appearances in head coaching history, Izzo also claimed the record for the most ever NCAA Tournament wins as the lower seed, with this his 16th.

He is one more Sweet 16 trip away from tying Louisville legend Denny Crum for the fifth-most, with only North Carolina's Roy Williams (19), Syracuse's Jim Boeheim (20), Michael Jordan's North Carolina coach Dean Smith (21) and Duke's Mike Krzyzewski (26) having more.

The seven-seed Spartans will next face three-seed Kansas State after they won the battle of the Wildcats 75-69 against six-seed Kentucky.

Reigning National Player of the Year Oscar Tshiebwe was monstrous with 25 points and 18 rebounds, while projected first-round draft pick Cason Wallace impressed with 21 points (nine-of-11 shooting), nine rebounds, four assists and two steals.

But their performances were not enough to lift Kentucky to the victory, as diminutive five-foot-eight point guard Markquis Nowell dropped a game-high 27 points and nine assists to carry Kansas State through.

Following his massive 28-point, 13-rebound showing in his side's opening-round win, Connecticut Huskies center Adama Sonogo starred again with 24 points (11-of-16 shooting) and eight rebounds in a 70-55 win over the Saint Mary's Gaels.

After Marquette, the top seed to fall Sunday was the three-seed Baylor Bears. Despite 30 points from Baylor guard L.J. Cryer, the Creighton Bluejays received a game-winning 30 points from Ryan Nembhard in the 85-76 triumph.

Nembhard is the younger brother of Andrew, who has been a rookie standout for the Indiana Pacers this season.

Following their stunning upset of one-seed Purdue, where they became the second 16-seed to ever advance past the first round, the Fairleigh Dickinson Knights were sent packing 78-70 by the nine-seed Florida Atlantic Owls.
