Al Jenkins began his pro career with the Cleveland Browns after he was made the second of Cleveland’s two third round picks (55th overall) in the 1969 NFL Draft. He spent 1969 and 1970 with the Browns, appearing in 13 games. In 1972, Jenkins made the Miami Dolphins, a team that would go undefeated on the way to winning the Super Bowl. Jenkins played in all 14 regular season games as a reserve guard for the Dolphins. The following year, he was with the Houston Oilers where he played in 13 games. In 1974, Jenkins moved to the new World Football League by signing with the Chicago Fire. Jenkins wore this jersey for road games with the Fire and it features numerous repairs around the shoulder areas.
Jenkins finished off his pro career with one final season in the troubled WFL in 1975, playing for the Chicago Winds until the league disbanded the franchise after two major investors pulled out following a 1-4 start. Jenkins was selected by the Southern California Sun in the Winds dispersal draft but never signed with the Sun. Jenkins instead signed with the Birmingham Vulcans on September 16, 1975 and played there until the entire league ceased operations in late October. In college, Jenkins was once named Associated Press Lineman of the Week after his coaches at Tulsa moved him from his guard position on the offensive line to defense for a game in 1967 versus the heavily-favored #10 ranked Houston Cougars. The Golden Hurricanes employed a 5-3-3 alignment over their base 4-4-3 defense in the 22-13 victory with Jenkins playing at nose guard that day. Jenkins racked up 15 unassisted tackles and was credited with 3 forced fumbles against what was the top rated offense in the nation at the time.
