The #2 ranked Oregon Ducks suffered their first loss of the season as they were upset by Arizona at home 31-24.True freshman Nick Wilson ran for two touchdowns and caught a scoring pass from quarterback Anu Solomon to help the Wildcats (5-0, 2-0 Pac-12) open the season with five straight victories for the first time since 1998.

Terris Jones-Grigsby plowed into the end zone from a yard out for the tiebreaking touchdown with 2:54 left, and Arizona held on after sacking Mariota and recovering his fumble.

It was the third time since 2007 that an unranked Wildcats team upset an Oregon squad ranked in the top five.
