What happened: Makhachev said Jones' unbeaten UFC run should not carry full weight in GOAT arguments because of two doping cases. He pointed to the Daniel Cormier fight that was later changed to a no contest after Jones tested positive for a turinabol metabolite. Jones answered on social media, and Makhachev replied that Jones has spent his career tied to breaking rules.

Why it matters: The exchange puts two of the sport's biggest resumes back at the center of the argument over how PED history should shape legacy. Both men have won and defended UFC titles in two divisions, giving the dispute more weight than a standard online feud. Makhachev is the reigning welterweight champion after wins over Jack Della Maddalena and Ian Machado Garry, while Jones walked away after beating Stipe Miocic in 2024.

What to watch: Watch for whether Jones answers again or other current champions step into the legacy argument. Any formal UFC response would give the feud more lasting weight.
