How many perfect brackets remain? Here's what to know of perfect brackets across men's and women's NCAA Tournaments so far:

Last year, there were only four brackets that remained perfect after the first two rounds of the women’s tournament.

The biggest upsets on Thursday — No. 12 McNeese beating No. 5 Clemson and No. 11 Drake knocking off No. 6 Missouri — eliminated a big chunk of brackets early. Then on Friday, No. 12 Colorado State beating No. 5 Memphis was the biggest upset of the day, though that only dwindled the number of perfect brackets down from 0.1% to 0%.

Big upsets are arguably one of the most exciting parts of March Madness, despite the pain it might bring your already-busted bracket.

Madness continues on Thursday with four Sweet 16 games, including No. 1 seed Duke and Cooper Flagg facing No. 4 Arizona.

NCAA Tournament action resumes Thursday as the Sweet 16 gets underway with four huge games that each bring compelling storylines. By night's end, just 12 teams will be left standing in the race to crown a 2025 national champion.

The Southeastern Conference set a record with 14 teams qualifying for the NCAA Tournament. Now the league has matched another mark: four teams through to the Elite Eight.

Which teams will join Alabama, Florida, Duke and Texas Tech in the Elite Eight? We find out Friday night as the Sweet 16 continues.
