Jon Jones has officially retired from the sport and Tom Aspinall is now the undisputed UFC heavyweight champion.

That’s according to UFC CEO Dana White, who broke the news during the UFC Baku post-fight press conference on Saturday following the promotion’s debut event in Azerbaijan. The stunning news came after Jones apparently called the UFC to tell them he was hanging up his gloves.

“Jon Jones called us last night and retired,” White said.
