In spring of 1986, Koloff started one of the biggest, most anticipated feuds in the history of Jim Crockett Promotions when he attacked NWA United States Heavyweight Champion Magnum T.A.. Following an incident where Magnum hit on-screen NWA President Bob Geigel for demanding an apology after T.A. started a brawl with Nikita during a contract signing (which started when the Koloffs berated Magnum's mother, who was present), T.A. was stripped of his title. The two were then booked in a best-of-seven series, which took place during The Great American Bash 1986 tour. The winner of the series would be declared champion. Koloff and T.A. wrestled all summer, ending up tied after six matches with one no contest. The final match took place on August 17 and featured run-ins by Kruschev and Ivan and several false-finishes. Nikita defeated T.A. to win the title.
