On a Thursday night that saw several top NCAA basketball teams stumble, No. 6 LSU narrowly managed to keep their perfect season intact, though No. 16 Tennessee took the Tigers to the brink in a close 89-87 conference battle.

The SEC's rising parity was fully on display as stars Jewel Spear and Talaysia Cooper posted 25 and 24 points, respectively, to try and put their surging Tennessee side on top.

Though the Vols chipped away throughout the game at LSU's nine-point first-quarter lead, it was Tiger junior Kailyn Gilbert who cemented LSU's win with a wild, last-second bucket, putting a bow on her 22 points off the bench.

LSU senior Aneesah Morrow also shined, registering 23 points and 21 rebounds — her NCAA-leading 16th double-double and second 20+ point, 20+ rebound performance this season.

Now 18-0, LSU is one of just three undefeated Division I college basketball programs this season, joining just No. 1 UCLA and No. 9 Ohio State in remaining unbeaten.

Seven top 25 NCAA teams fall on Thursday

LSU's victory over Tennessee was just one of seven NCAA basketball games to see ranked teams fall on Thursday night. No. 5 Texas annihilated No. 18 Alabama to the tune of 84-40, while No. 19 UNC and No. 24 Cal registered upsets of No. 14 Duke and No. 21 NC State, respectively.

Unranked teams also did damage in the Top 25, with Illinois downing No. 23 Iowa and Mississippi State bouncing back from the 95-68 shellacking they took at the hands of No. 2 South Carolina on Sunday by taking down No. 10 Oklahoma 81-77.

That said, No. 13 Georgia Tech suffered the most consequential defeat after seeing their unbeaten season disappear in a 105-94 double-overtime loss to unranked Virginia Tech.

Yellow Jacket junior Kara Dunn's game-leading 33-point, 10-rebound double-double and teammate Tonie Morgan's 28 points kept Georgia Tech alive throughout much of the back-and-forth battle.

However, 17+ point showings from Virginia Tech's entire starting lineup, not to mention a late, stifling defense that allowed them to outscore Georgia Tech 13-2 in the second overtime period, ultimately secured the win for the Hokies.

NCAA basketball weekend rife with upset potential

With 23 ranked NCAA teams facing unranked opponents this weekend, the potential for upsets is high, though the lone ranked pairing is a highly anticipated Top-5 affair.

The SEC will take center court again, as No. 5 Texas takes on defending national champions No. 2 South Carolina on Sunday.

Ahead of the tense matchup, guard Rori Harmon promised that the Longhorns are "going to make sure it's a knockdown, drag out."

"It's going to be a battle, and we look forward to the battle," said South Carolina head coach Dawn Staley, referencing her team's tough conference slate.

With all eyes on the stacked midweek NCAA basketball slate, No. 4 USC eked out a gritty road win over No. 8 Maryland on Wednesday, shattering the Terrapins' undefeated season in the process.

Despite guard Shyanne Sellers's game-leading 26 points and forward Christina Dalce posting the contest’s only double-double, the Terps fell 79-74 in their first meeting with the Trojans since 1995.

USC rallies the troops

New Big Ten team USC had to band together to overcome Maryland's defense, which stifled star JuJu Watkins's firepower by holding her to 7-for-19 from the field and 1-for-5 from beyond the arc with eight turnovers. That said, Watkins still managed to match forward Kiki Iriafen's team-leading 21 points before fouling out in the final minute.

With star guard Talia von Oelhoffen unavailable due to injury, USC’s No. 1-ranked freshman class stepped up. Guards Kennedy Smith, Avery Howell, and Kayleigh Heckel each added double-digit points to push the Trojans over the line.

"We just kind of have this unwavering confidence in ourselves," Watkins said after the game. "It was just a matter of coming together and closing the game out."

Big Ten ruled Wednesday's NCAA court

Unlike Maryland’s unbeaten record, No. 9 Ohio State’s undefeated season narrowly survived arch-rival No. 25 Michigan on Wednesday night. After falling behind 44-31 at the half, the Buckeyes put together a second-half surge to snag the 84-77 win. Freshman guard Jaloni Cambridge led Ohio State's charge with 29 points.

Elsewhere, unranked Nebraska handed No. 20 Michigan State a second conference loss on Wednesday. Buoyed by senior Alexis Markowski’s 28 points, the Huskers channeled a second-quarter lead to down the Spartans 85-80.

LSU to test perfect NCAA season against tough Tennessee side

The top-ranked midweek NCAA basketball action continues on Thursday, headlined by a tightly matched high-octane showdown between two historic SEC heavy-hitters.

No. 6 LSU faces their toughest test so far when they visit No. 16 Tennessee, a team that leads the nation in offensive scoring and rebounding, three-pointers, and forced turnovers.

"[Tennessee's] style of play is like nothing I’ve ever seen," LSU head coach Kim Mulkey said ahead of the game.

"They score a lot of points and they make you play fast with their press. It’s going to be quite a challenge to keep them from scoring in the '90s. We score a lot of points, too, [but] I’ve got to stress defense. At some point we’ve got to try to stop them from scoring as much as they’d like to score."

Despite the numbers, the Vols suffered their first loss of the season on Sunday — a one-point stumble against No. 10 Oklahoma. They'll look to avenge their loss by halting the 17-0 Tigers' unbeaten streak.

More ranked college clashes take center court on Thursday

Shortly after LSU takes on Tennessee, longtime ACC rivals No. 19 UNC and No. 14 Duke will meet for the 109th time. The host Tar Heels hold a narrow edge with a 55-53 all-time record against the Blue Devils, and will enter the clash with a redemption plan after falling 76-66 to No. 3 Notre Dame on Sunday.

With a significantly shorter history on the line, one-loss teams No. 5 Texas and No. 18 Alabama will face-off in Thursday's SEC nightcap, with the Tide rolling into Austin to seek a program-first win over their newest conference foes.

Last season’s Sweet Sixteen showdown was the pair’s first meeting since 1984, and Alabama has never beaten or even scored more than 56 points against the Longhorns throughout their three all-time meetings.
