Jack Krueger started out wrestling in the Kansas City territory under his own name in the late 1975. Kruger worked as an enhancement wrestler on televised matches emanating from that territory. He later donned a mask and became one half of the Bounty Hunters tag team.
Jack soon settled in Dick the Bruiser's World Wrestling Association (Indianapolis) (WWA) in 1981. Under the moniker of Sheik Ali Hassan, Krueger has his most successful run as a wrestler, teaming up with Abdullah The Great to win the WWA Tag Team Championships in June 1982. He returned to the area after an extensive stay in Memphis to team with Jerry Valiant to win the WWA tag team titles for a second time in 1983.
Krueger had two stints in the Memphis Continental Wrestling Association (CWA) territory. In 1980 as Sheik Abdullah Hassan teaming with Paul Ellering to win the AWA Southern Tag Team Championship.

Under the name of Sheik Abdullah Ali Hassan captured the NWA Pacific Northwest Heavyweight Championship from Brett Sawyer in December 1982, he lost the title to young up and comer, Curt Hennig in May 1983.
After finishing his stay in the Pacific Northwest, he moved to NWA Central States, this would prove to be Krueger's most successful stay. Teaming with Roger Kirby as "The Sheiks" and winning the NWA Central States Tag Team Championship on two occasions.
Jack joined the World Wrestling Federation (WWF) roster as an enhancement talent in late 1985, he reformed his tag team with Roger Kirby with little success. In 1986 Krueger was involved in the "Kamala top rope splash" angle on WWF Television, where he was injured and stretchered out of the arena after a Kamala top rope splash. Kruger was interviewed where he said "he'd never sign to wrestle Kamala again" in fear of the splash.
