Tuesday was the first time a No. 1-ranked team came into Bud Walton Arena, and the game lived up to the hype. Auburn’s 19-game winning streak went down as the Razorbacks pulled off one of the biggest upsets in college basketball this season.

After 14 ties and 15 lead changes in regulation, Auburn and Arkansas went to overtime, as they exchanged baskets in the final minute of regulation. After the Razorbacks built a 12-point lead midway through the first half, only for Auburn to climb to within 3 points at halftime, Arkansas came back to prevail 80-76, and extend its winning streak to 9 games. Arkansas fans stormed the court at the buzzer.

“They danced on our logo before the game, we watched that,” Arkansas coach Eric Musselman told Alyssa Lang on ESPN2 after the game.

Arkansas had a 6-0 run in overtime as Auburn went on a 2:00 drought. But Auburn’s Jabari Smith had a pair of 3-pointers in overtime to make it tougher on Arkansas and finished with 20 points.

JD Notae poured in 28 points for Arkansas, as the Razorbacks had 3 players in double figures. Wendell Green Jr. for Auburn added 20 points as 3 Tigers reached double figures. Auburn big man Walker Kessler had 16 points and 19 rebounds before he fouled out with 1:30 remaining in overtime.

Arkansas had a big run in the first half, as the Razorbacks went on a 16-2 burst, including 7-0, over 5:58 to build a 10-point lead as Auburn appeared to struggle with its point guard being out coupled with the raucous environment at Bud Walton Arena.

Auburn then called timeout, but committed an offensive foul when action resumed.

Auburn had been in this situation before in SEC play, as the Tigers had double-digit deficits against Ole Miss (14), Kentucky (12) and Missouri (10). And the Tigers came into Tuesday as the only team in the country this season that hadn’t lost a game in regulation. That stat lived another day, but Auburn suffered its second loss of the season.

One notable lineup change was Auburn played without guard Zep Jasper, who was out for the second straight game with a non-COVID-related illness. Still, the Tigers were off to their second best start in program history at 22-1 overall and were on a nation-leading 19-game win streak.
