It’s not yet midnight for the Princeton Tigers.

The No. 15 seed moved on to the Sweet 16 after taking down No. 7 Missouri in the second round Saturday, 78-63.

Princeton dominated the first half, building a 14-point lead. But Missouri got back-to-back buckets to cut it to a seven-point deficit. But the 15th-seeded Tigers got off to a hot start in the second half, and they never looked back, leading by as many as 21 points.

The Tigers are the fourth 15 seed to advance to the Sweet 16, joining last year’s St. Peter’s Peacocks (also from New Jersey), Oral Roberts from 2021 and 2013’s Florida Gulf Coast squad.

"This is awesome for our school. Sweet 16 means a lot to our crew here. This is really special," Princeton head coach Mitch Henderson said on the broadcast after the win.

"These guys come here to win. It’s the best school in the country. … We’re so thrilled to be here but not surprised."

Henderson did not reach the Sweet 16 when he played for Princeton, so he's savoring this ride.

"I've always dreamed of playing deep into the tournament. As a player, got to the second round a couple times. Never got beyond it," he said after the game. "I feel like these guys, it's unbelievable."

"I told them at halftime, 'We're going to get on that flight.' We were up seven at half," he added. "We had coughed up seven points. I said, 'You know we're going to get on that flight [back to New Jersey], no matter what. When we get on that flight, we're going to be us.'

"We felt like the best version of us could beat the best version of them. They did it. Yes, we're going to the Sweet 16. But this is a really unique group. I think, in the tournament, each group has a special life. This one has a really special life. So I'm just, again, so proud of 'em."
