The last two times Arizona has played Nebraska were both Holiday Bowls. The 2009 version did not go so well, but that 1998 one was pretty good. The only other time they've played came in 1961, when the two schools played to a 14-14 tie in Lincoln. Arizona went 8-1-1 that year.
As for K-State, Arizona is 5-1-1 all-time against those Wildcats, but they have not played since 1978. Those games will be played on September 24th, 2024 in Manhattan, and September 13th, 2025 in Tucson.
