In the summer and fall of 1975, Jacobs wrestled for promoter Fritz Von Erich's World Class Championship Wrestling where he faced Steve Strong, Skip Young, John Tolos, Mike Paidousis, Hans Schroeder, Bruiser Blackwell, Buddy Wolfe, and Red Bastien. That same year, he wrestled Superstar Billy Graham at the Greensboro Coliseum on 3 April 1975. In Georgia, Jacobs feuded with another young wrestler, Randy Savage, during the summer of 1977. During one of these meetings, he and Roberto Soto defeated Savage and Bill Howard in a tag team match at the Atlanta City Auditorium on 3 June 1977. He was also brought to Maple Leaf Wrestling by Toronto promoter Frank Tunney where, on 22 October 1978, he fought British wrestler Geoff Portz to a lime-limit draw at the Maple Leaf Gardens. When George Scott left for the World Wrestling Federation in 1981, Ole Anderson took over as head booker for the promotion. Due to personal differences with Anderson, Jacobs was no longer booked in the territory.
