The other finalists for the Walter Camp, which is voted by the sports information directors and head coaches from the 129 FBS schools, were Washington quarterback Jake Browning and Alabama defensive lineman Jonathan Allen.
Jackson accounted for 51 touchdowns this season and averages 410 yards per game in total offense. He is the favorite to win the Heisman on Saturday night in New York.
The last three players to win the Walter Camp — Alabama's Derrick Henry, Oregon's Marcus Mariota and Florida State's Jameis Winston — have also won the Heisman.
Jackson also came away with the Maxwell Award Thursday night for being the most outstanding collegiate player.
