This win also marked the first victory for head coach Eric Morris at the school. Quarterback Drew Mestemaker led the Cowboys with 317 passing yards and two touchdowns, alongside 109 rushing yards and a touchdown, including a decisive 10-yard run in the fourth quarter. Oregon, a preseason national title favorite, struggled offensively, with quarterback Dante Moore completing 14 of 29 passes for 191 yards and two touchdowns. The loss ends Oregon’s 41-game winning streak against unranked opponents and significantly impacts their standing in the College Football Playoff race. The defeat has intensified scrutiny regarding head coach Dan Lanning’s ability to lead the program to a national championship, particularly as the Ducks navigate the 2026 season following a period of inconsistent performance. Following the game, Oklahoma State fans stormed the field and celebrated by placing a dismantled goalpost into a campus pond. ## Timeline ### 2026-09-12: College football sees controversy in Michigan win and Oregon upset College football faces early-season turbulence as Michigan defends its controversial win over Western Michigan while No. 6 Oregon suffers an upsetting loss to Oklahoma State. 4 sources. https://clstr.news/cluster/college-football-sees-controversy-in-michigan-win-and-oregon-upset ### 2026-09-11: Oklahoma State upsets No. 6 Oregon 39-31 Unranked Oklahoma State upset No. 6 Oregon 39-31, ending a 21-game FBS losing streak behind Drew Mestemaker’s standout performance. 20 sources. https://clstr.news/cluster/oregon-ducks-face-oklahoma-state-in-week-2-college-football-matchup --- Cite as: Oklahoma State upset of Oregon Ducks.
