Oregon’s winning streak came to an abrupt end Saturday, with Oklahoma State pulling off the first major upset of the season in a 39-31 victory.
The result snapped the Cowboys’ 21-game skid against FBS opponents and gave first-year Oklahoma State coach Eric Morris his first win with the program. It also ended Oregon’s 41-game winning streak against unranked opponents.
The breakthrough sparked a memorable celebration in Stillwater, especially after Oklahoma State went 1-11 last season and opened this year with a 24-10 loss to Tulsa.
