  • UFC star Anthony "Rumble" Johnson had an estimated net worth of $4 million

UFC star Anthony "Rumble" Johnson passed away Sunday following a battle with multiple illnesses. He was 38.

At the time of his death, the mixed martial artist had an estimated net worth of $4 million, according to Celebrity Net Worth (CNW).

Johnson made his fortune from his professional fight earnings and endorsement deals.

In 2015, he earned $500,000 for a headliner fight at UFC 187 against former UFC light heavyweight champion Daniel Cormier despite losing in the third round, MMA Junkie reported. The figure was only the estimated base salary and did not include deductions from insurance, licenses, taxes or other special discretionary UFC bonuses, the outlet noted.

In addition to his earnings from professional fights, the Georgia-born mixed martial artist also scored an endorsement deal with beverage company FBEC Worldwide in 2015 for its hemp-based energy shot WolfShot. At the time, Johnson was the No. 2 ranked UFC light heavyweight contender in the world, according to PR Newswire.

Johnson was an all-around player, competing in the welterweight, middleweight, light heavyweight and heavyweight divisions. He made his UFC debut in 2007 in a fight against Chad Reiner, whom he defeated in only 13 seconds. It was in 2016 that he made his professional MMA debut with a win over Jonathan Romero.

The mixed martial artist was awarded numerous recognitions throughout his career, including "Knockout of the Night" honors for his fights against Kevin Burns and Charlie Brenneman in 2008 and 2011, respectively. He was also recognized with "Fight of the Night" honors in 2009 despite losing to Josh Koscheck.

Johnson also received the "Performance of the Night" title for four battles. The first came in 2014 when he beat Antonio Rogerio Nogueira, while the second came in the succeeding year when he defeated Alexander Gustafsson. He also earned the title when he won over Jimi Manuwa in 2015 and Ryan Bader in 2016.

Johnson went 13-6 in the UFC from 2007 through 2017 and compiled a 23-6 overall MMA record, including 17 victories by knockout, before he died.

Before competing in the MMA league, Johnson was a junior college national champion when he competed in the National Junior College Athletic Association amateur wrestling.

Johnson announced his retirement from the MMA in 2017 but made a surprise comeback in the Bellator Light Heavyweight World Grand Prix four years later, CBS Sports reported.

Johnson's return to action in the Bellator cage, which saw him knocking out Jose Augusto in May 2021 during the first round of the tournament, was considered his last fight. Illness later forced him to withdraw from his title fight with Vadim Nemkov in the semifinals.

Months after his final fight, Johnson posted on his Instagram account that he needed "many prayers," revealing that he was battling an illness that he did not reveal at the time.

In late October of the same year, his manager, Ali Abdelaziz, spoke with ESPN and explained that Johnson was "going through some health problems," but also did not disclose the athlete's illness.

According to Yahoo Sports, Johnson died from organ failure due to non-Hodgkin's lymphoma and hemophagocytic lymphohistiocytosis, a rare disorder of the immune system.
