Rumble was ranked #1 in his weight class before he retired. He officially left the UFC in 2020 to join Bellator MMA, according to TMZ.
“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,” fellow fighter Daniel Cormier tweeted following Rumble’s death.
The fighter’s cause of death has not yet been released, according to reports.
