WBC heavyweight champion Tyson Fury has offered Anthony Joshua the chance to fight for his belt before the end of this year.
Fury, 34, is looking for an opponent after rival Oleksandr Usyk, the WBO, WBA and IBF champion, suggested he will not return to the ring until 2023.
Joshua, who was beaten by the Ukrainian in Saudi Arabia last month, responded to Fury's challenge by saying he would be "ready in December".
Fury said in April he was retiring.
But in a video posted on social media on Monday, he said: "You've all heard that I'm going to be fighting within the next few months, and before I announce an opponent I need to do this just in case.
Fury had said he was retiring after beating Dillian Whyte in April, and also reiterated that claim just last month.
On Saturday, Fury said he would announce his next opponent next week - but confirmed it will not be Usyk.
Uysk said on Friday of a fight with Fury: "It won't happen this year, that's for sure. I'm totally healthy and don't have any injuries, but I have old traumas which have resurfaced, and which need to be treated. I will need up to two months to recuperate."
