Quarterback Anthony Grigby, Jr. threw for 319 yards, finishing 26-for-35 and finding wide receiver Tayvion McCoy for his fourth and final touchdown pass with nine seconds remaining Friday evening as the Cal Poly football program opened the 2026 season and Big Sky Conference action with a 38-34 victory against Idaho at Mustang Memorial Field.
During an evening when Cal Poly retired the No. 74 of Pro Football Hall of Fame legend and Mustang alum John Madden at halftime and set a new program attendance record with 11,186 fans, Cal Poly fell behind, 34-31, with 63 seconds remaining after Vandals kicker Owen Forsman converted a 40-yard field goal attempt.
With Cal Poly starting its final drive on its own 23-yard line, Grigsby completed a 41-yard pass to McCoy before another completion brought the Mustangs to the Idaho 36. On fourth-and-eight, Grigsby found McCoy from 34 yards for the game-winning touchdown.
