Three Top 10 NCAA basketball teams suffered big upset losses on Thursday, shifting late-season momentum to the sport's underdogs ahead of next week’s conference tournaments.

No. 3 Notre Dame fell 86-81 to No. 24 Florida State, marking the Irish's second straight loss since reaching No. 1 in the AP Poll on February 17th.

"Just really frustrated with our performance defensively tonight," Notre Dame coach Niele Ivey after last night’s game. "I didn’t think that we were locked in for four quarters."

No. 7 LSU and No. 8 UNC also saw tough results, with the Tigers falling in a narrow 88-85 overtime battle to No. 20 Alabama while the Tar Heels stumbled 68-53 to in-state rival No. 16 Duke.

Even No. 1 Texas faced some adversity, eking out a 68-64 win after unranked Mississippi State pushed the Longhorns to the brink.

All in all, as the hyper-competitive 2024/25 women's college basketball season draws to a close, building exhaustion, waning focus, and minutes management are inducing game-changing upsets — putting the country’s top teams firmly on notice.

Conference titles on the line in final NCAA games

While most of Thursday's upsets affect seedings further down conference tables, Notre Dame's loss puts the Irish in danger of losing the ACC tournament’s No. 1 seed right at the finish line.

Notre Dame now sits alongside No. 9 NC State atop the conference table, with the Wolfpack holding a potential tie-breaking head-to-head advantage over the Irish. The only way Notre Dame can now book the top ACC tournament spot is with a win over No. 25 Louisville plus an NC State loss against unranked SMU this Sunday.

Even more, Notre Dame could now lose their projected top-seeded entry into the 2025 NCAA tournament.

Along with the ACC trophy, regular-season titles in the SEC, Big 12, and Big Ten will now come down to weekend finales. The Big East's No. 5 UConn stands alone as the only major conference team to have already secured their title.

Similar to the ACC, the No. 1 SEC seed relies on a pair of Sunday games featuring the conference's two top contenders: No. 1 Texas and No. 6 South Carolina.

The Big 12 and Big Ten, however, finish the season with table leaders meeting in winner-take-all finals this weekend. The Big Ten title will be decided in Saturday's clash between No. 4 USC and No. 2 UCLA, before No. 10 TCU and No. 17 Baylor will battle for the Big 12 trophy on Sunday.

In the pair's first rounds earlier this season, USC and TCU emerged with wins over their respective conference foes.

How to watch top women's college basketball games this weekend

The country's best NCAA teams are all aiming to take care of conference business this weekend, pushing for top seeds and eyeing deep postseason runs.

Saturday's spotlight belongs to No. 4 USC and No. 2 UCLA, with the crosstown rivales' rematch determining the Big Ten title. USC tips off against UCLA at 9 PM ET, live on Fox Sports.

Then, Notre Dame kicks off ESPN's Sunday coverage with a decisive game against No. 25 Louisville at 12 PM ET.

Sunday's DI finale belongs to the Big 12, where No. 10 TCU takes on No. 17 Baylor at 6:30 PM ET, airing live on FS1.

The PWHL is continuing to break records, as Sunday's 2025/26 Takeover Tour stop in Washington, DC, saw 17,228 fans pack into Capital One Arena to see the No. 2 New York Sirens top the No. 4 Montréal Victoire 2-1 — setting a new US women's hockey attendance record in the process.

The benchmark surpasses the previous US record set this past November, when the Seattle Torrent welcomed 16,014 fans to their inaugural home opener.

Sunday's DC crowd also sees the US mark inch closer to the overall professional women's hockey attendance record, set in April 2024 when 21,105 PWHL fans sold out Montréal's Bell Centre to watch the Victoire take on the Toronto Sceptres.

"Washington, DC, showed up in such a big way, and the energy our fans brought into the arena turned this game into something truly special," PWHL EVP of business operations Amy Scheer said of the first-ever PWHL game in the nation's capital. "Moments like this capture the joy of our sport and the momentum behind the league."

The third-year league is currently racing through its best-attended month on record, drawing more than 154,000 fans across the last 16 games while averaging crowds of 8,726 across all 49 games so far this season.

The Kansas City Current delivered some concerning news this week, with the NWSL club revealing that star striker Temwa Chawinga remains sidelined with an hip adductor injury while the league's 2026 preseason gets underway.

The team currently lists the reigning back-to-back NWSL MVP under a season-ending injury (SEI) designation, a category earned after Chawinga picked up the injury in mid-October, leaving the Kansas City attacker benched for the Current's quarterfinal loss to eventual 2025 NWSL champions Gotham FC.

"It's hard because of the nature of the injury," incoming Kansas City head coach Chris Armas told The Athletic last week. "With Temwa, we've got to be very careful, but she's looking great and doing lots of good work on the return to play."

Also on the Current's SEI list is standout winger Michelle Cooper, with the 23-year-old rising USWNT star suffering a foot injury in Kansas City's final regular-season match of 2025.

"It was a little bit of a tough ending here after, honestly, an amazing historic season," said Armas. "Hopefully they are back as soon as possible, but it's still unclear."

Both Chawinga and Cooper will have some time to recover before Kansas City kicks off their 2026 NWSL regular season against the Utah Royals on March 14th — with teams allowed to lift a player's SEI status any time once the season begins.

The world's top tennis stars are rolling in Melbourne, as the first round of the 2026 Australian Open wrapped early Tuesday morning with only a few ranked seeds suffering early defeats.

World No. 15 Emma Navarro was the highest-ranked US player to fall in the first round, with the 24-year-old exiting the season's first Grand Slam in a 6-3, 3-6, 3-6 loss to Poland's No. 50 Magda Linette on Sunday.

No. 11 Ekaterina Alexandrova also stumbled in the first round, with her Melbourne run ending in a three-set loss to Turkey's No. 112 Zeynep Sönmez on Saturday before No. 68 Peyton Stearns ousted fellow US star and 2020 Australian Open champion No. 30 Sofia Kenin in straight sets on Sunday.

Many contenders still remain in the hunt, however, as the entire WTA Top 10 cruised through their opening matchups to advance to the Slam's second round.

That said, fans will miss out on one highly anticipated showdown, as wild card entry Venus Williams's first-round loss ended the 45-year-old tennis icon's path to a second-round clash with US favorite No. 3 Coco Gauff.

The 2026 Australian Open continues when the Slam's second round kicks off with a Tuesday night slate that features stars like No. 1 Aryna Sabalenka, No. 3 Coco Gauff, and No. 7 Jasmine Paolini.

Tuesday's action begins at 7 PM ET, with all Melbourne matches airing live across ESPN platforms.

The ongoing dominance of UConn basketball has started to break records, as the top-ranked Huskies humbled unranked Notre Dame 85-47 on Monday — keeping their perfect 2025/26 NCAA season intact.

Monday's 38-point margin of victory marked the largest in the teams' 20-year rivalry, with the win also snapping the Huskies' three-game head-to-head losing streak against the Fighting Irish.

"UConn showed why they're the best team in the country," Notre Dame head coach Niele Ivey said postgame.

Even more, UConn sophomore forward Sarah Strong added her own individual history to Monday's tally, becoming the third-fastest Husky to reach 1,000 career points, with the 19-year-old trailing only program legends Maya Moore and Paige Bueckers — who each did so in 55 games to Strong's 59 — in the race to reach that stat.

"I would love to see if anybody has scored 1,000 points by taking less shots than she's taking," said UConn head coach Geno Auriemma. "She's so efficient."

"It means a lot to me I guess, but I wouldn't be able to do it without my teammates," Strong said after leading the Huskies with an 18-point, 11-rebound double-double on Monday night.

UConn now returns to Big East play, with the No. 1 Huskies taking on unranked Georgetown at 7:30 PM ET on Thursday, airing live on TNT.
