Longshore did not see playing time again until the final regular season game of his college career on December 6 against the winless Washington Huskies when he stepped in for Riley during the second and third quarters. He threw for 84 yards and his 50th career touchdown pass, which moved him up to fourth overall in touchdown passes. He was replaced in the fourth quarter by third-string quarterback Brock Mansion when Cal began playing its backup players to give them some game experience. Longshore's final collegiate game came when he was picked to start for the 2008 Emerald Bowl over Riley, his performances in practice and health being cited as factors. He passed for 121 yards and the game-winning touchdown to freshman tight end Anthony Miller, moving him up to third place alongside Troy Taylor for career touchdown passes.
