Floyd Mayweather Jr has said he is coming out of retirement.
The 42-year-old American has not fought since the 50th fight and 50th win of his career in August 2017.
That was over UFC star Conor McGregor, a fight found under boxing rules.
A rematch, possibly under UFC rules, has long been touted, as have traditional ring returns against a number of opponents.
In an Instagram post, Mayweather – a five-weight world champion – simply said: "Coming out of retirement in 2020".
And hinting that his claimed return will be something more than a boxing one, he posted another picture with UFC boss Dana White, who helped promote the McGregor fight, saying the pair were "working together again".
