Buffalo secured a dramatic 23-20 overtime victory against No. 23 Northern Illinois, with Upton Bellenfant's 37-yard field goal sealing the upset. This marks Buffalo's first win over a ranked opponent since 2008 and their first MAC Conference win under new head coach Pete Lembo. Northern Illinois, fresh off an upset victory over then-No. 5 Notre Dame, struggled offensively, managing only six points in the second half. Key plays included a blocked field goal by Buffalo's Marquis Cooper and a crucial interception by Shaun Dolac. Despite strong performances from NIU's Antario Brown and Ethan Hampton, the Huskies failed to capitalize and will likely drop out of the AP Top 25. Buffalo improved to 3-1, while NIU fell to 2-1.
