LEWISBURG, Pa. -- CJ Williams rushed for 154 yards and three touchdowns, and Bucknell enjoyed a day of milestones with a 48-10 upset of FCS-ranked Lehigh on Saturday.

With their first Patriot League win since 2011, the Bison (3-4, 1-2) also snapped a 15-game losing streak to the Mountain Hawks (6-2, 1-1) in a series in which the teams have played each other every year since 1950. It was the first time Bucknell has defeated a ranked team since 2009.

Brandon Wesley, Bucknell's career passing leader who played in a reserve role last week and made his first start after missing three games with a leg injury, threw for 213 yards and a score and ran for a touchdown. Will Carter had 130 yards receiving as the Bison piled up 509 yards total offense. They led 27-3 at halftime.

Lehigh had just 85 yards rushing, lost a fumble and had four passes intercepted.
