Arizona tasted its first defeat of the season after collapsing against Kansas, 82-78, at Allen Fieldhouse on Monday.

The top-ranked Wildcats were in control of the game until the Jayhawks, who played without NBA prospect Darryn Peterson due to flu-like symptoms, mounted a rally with 10 minutes left in the second half.

Kansas grabbed the lead, 65-64, courtesy of Flory Bidunga's layup. From there, the momentum completely swung to the ninth-ranked Jayhawks, who held on for the win. They improved to 19-5, including 9-2 in the Big 12.

Arizona, meanwhile, fell to 23-1, including 10-1 in the Big 12.

Fans were shocked after the Wildcats blew the game.

“As an honest U of A fan since 2023, I speak for all of us fans when I say we are frauds. We played an easy schedule until now and got blown out by the first real team we faced!” said @RatioLilBro___.

“Koa Peat (got) exposed tonight. Playing against guys who are pro-size. Can't shoot it, can't finish in the paint. He better develop a jumper or he’s D-Will (Derrick Williams) all over again,” added @Justwinjo.
