CSU, Wyoming cancel 2027 football matchup, ending historic rivalry streak

Colorado State University (CSU) and Wyoming will not face each other in football during the 2027 season, ending a continuous rivalry dating back to 1946. The Border War series has been held annually since World War II, with the exception of a break from 1943 to 1945. Conference realignment has led to scheduling conflicts, as CSU moves to the Pac-12 while Wyoming remains in the Mountain West. Although a 2026 game has been scheduled, 2027 will mark only the 11th season since 1899 without a matchup between the two teams. CSU will also have no rivalry games scheduled in 2027. They signed a deal for annual matchups from 2028 to 2036, but no agreement was reached for 2027 to accommodate full nonconference schedules.
