Bronko Sandor Lupsity (December 25, 1925 – August 11, 2007) was a Hungarian-born Serbian Canadian professional wrestler, manager, referee and promoter. Known by his ring names Bronco or Bronko Lubich, he and Aldo Bogni were veteran "heels" under manager "Colonel" Homer O'Dell competing in regional territories for the National Wrestling Alliance in Canada, the Pacific Northwest, Midwest and Southeastern United States throughout the 1960s. He and Bogni were particularly active in the Charlotte-area where they feuded with "The Flying Scotts" (George and Sandy Scott). They also had memorable feuds with George Becker and Johnny Weaver, Rip Hawk and Swede Hanson, Lars and Ole Anderson and Mr. Wrestling and Sam Steamboat.

Lubich also appeared as both a wrestler and manager in Texas during the early 1960s, most notably as the manager and cornerman of then NWA United States Heavyweight Champion Angelo Poffo from 1961 to 1964, and was often known to use his cane as a foreign object to help his men score victories. It was in this role that he became a well-known booker and promoter in the Dallas-Fort Worth area. He spent his last year as an active wrestler in Texas teaming with Chris Markoff where the two feuded with Mr. Wrestling and George Scott, and Johnny Valentine and Wahoo McDaniel.

After his retirement, he joined Fritz von Erich's World Class Championship Wrestling as head referee and part of the booking team for the promotion until its close in 1990. He is remembered by modern wrestling fans as one of its most visible referees, especially after WCCW began airing on televised events, and was involved in several major angles and storylines in the promotion. He was the official for many high-profile matches including the long-running feud between The Freebirds vs. the Von Erich family. He was also recognizable by his distinctive "slow counts" when a wrestler attempted a pinfall.

He was considered a highly respected official by wrestlers in the territory, according to interviews with former WCCW mainstays Scott Casey and Bill Mercer, and advised fellow wrestlers on both their professional careers and financial matters. Lubich, with Skandor Akbar, also had a small part in influencing the careers of several younger up-and-coming wrestlers including Mick Foley, "Stone Cold" Steve Austin, and manager Percy Pringle.

Lubich was born Branko Sandor Lupsity (Lupšić in Serbian) in Battonya, Hungary on December 25, 1925. His father (Mihailo) moved to Canada in 1926 and was eventually able to save enough money to bring his family over by boat to Montreal where they settled in December 1937. During his teenage years, he began working out with his friends at the local YMCA and took up amateur wrestling. He excelled in the sport and was selected to represent Canada in the 1948 Olympic Games, but he did not compete, having broken his arm while in another competition prior to the Olympics.

Although choosing to continue his amateur career, he also started work at an aircraft factory shortly after to support his family. It was while working out at the Montreal YMCA that he met local wrestlers Harry Madison and Mike DiMitre who suggested a career in professional wrestling. He was initially trained by DiMitre and made his professional debut in 1948. At 6-foot, 175 pounds, he spent his early career as a lightweight wrestler under the name Bronko Lubich and began teaming with Angelo Poffo by the late 1950s. In 1959, during a match between Poffo and Wilbur Snyder in Detroit, the referee was knocked unconscious. When Snyder attempted a pinfall, Lubich entered the ring and knocked out Snyder with his cane and revived the referee in time for Poffo to score a pinfall instead. This was the first time a manager had directly interfered in a wrestling match and, at the time, was one of the biggest televised angles. A rematch between Poffo and Snyder at the Olympia Stadium was attended by 16,226 people.

In 1961, Lubich made his debut in the Dallas area as the manager of Angelo Poffo. For three years, the pair would become one of the most hated "heels" in the territory. On a number of occasions, his interference saved Poffo from losing the NWA United States Heavyweight Championship. He and Poffo also held the WCWA Texas Tag Team Championship defeating Pepper Gomez and Dory Dixon in Houston, Texas on May 12, 1961. They held the titles for a month before losing them back to Gomez and Dixon on June 1. He and Poffo left the territory undefeated in 1964, Lubich moved on to Mid-Atlantic territory where he would remain for the majority of his career.

It was during this time that he was teamed with Aldo Bogni, in part due to the advice of promoter Jim Crockett, Sr., with their in-ring personas portraying hostile foreign wrestlers. They were joined by manager "Colonel" Homer O'Dell, and later George "Two Ton" Harris, who quickly became one of the top "heel" tag teams in the territory. O'Dell reportedly carried a revolver and sometimes fired it behind the arena to scare off fans who sometimes waited for them outside after the event. He and Bogni were later "sold" to Harris who participated in 6-man tag team matches with them.
