As a collegiate player at Washington State in the Pac-8, Jackson was a running back and kick returner for head coach Jim Sweeney[2][3][4][5][6] During his senior season in 1971, he rushed for 1,189 yards on 177 attempts (6.7 avg, 1st in Pac-8)[7] and was named First-team All-Pac-8 and All-Coast.[8] His 2,118 all-purpose yards in 1971–1,189 on the ground, 744 in kickoff returns and 185 receiving—remains the all-time WSU single-season record. He returned two kickoffs for TDs and also scored on a fake punt that season. He is a member of the WSU Athletics Hall of Fame.[8]
After five years with the Bengals, Jackson was traded to the Denver Broncos in March 1977, and that season the Broncos won the AFC title and advanced to Super Bowl XII. Jackson started the game, but the Broncos lost to the Dallas Cowboys 27–10.
Injured with a muscle bruise for much of the 1980 season, he was waived in late November and picked up by the San Diego Chargers.[9]
