Johnson competed in the UFC in welterweight, middleweight, and light heavyweight divisions. Known as one of the most feared punchers in the sport. He was 3-0 when he debuted in the UFC on June 12, 2007, knocking out Chad Reiner in just 13 seconds in Hollywood, Florida.

“Rumble” scored 17 of his 23 MMA wins by knockout.

MMA’s Daniel Cormier, who faced Rumble in the Octagon shared a special message about his former opponent.

“Rest Easy my brother. For a guy who struck fear in so many peoples heart Anthony Johnson was a caring person. From random text to check ins during loss. What a person he was, Rumble will be missed. Sometimes life doesn’t seem fair. Horrible news.”

Anthony “Rumble” Johnson Revealed Illness In 2021

Johnson last fought at Bellator 258 in May 2021, scoring a knockout win over José Augusto Azevedo. That earned him a light heavyweight title shot against Vadim Nemkov the following month at Bellator 268, but Johnson went on to withdraw with what was described as an undisclosed illness.

At that time, Johnson shared to Instagram how he wished he could go into detail about how sick he “truly” felt. He asked for prayers and support of friends and family.

He was 38 when he died. May he rest in peace.
