Former UFC heavyweight champion Francis Ngannou posted pictures of his three possible boxing opponents on his social media.
"Who's next? I choose," the Cameroonian signed the picture.
The picture shows Tyson Fury, Anthony Joshua and Deontay Wilder.
Ngannou, 36, had his last fight in MMA against Ciryl Gane in January 2022 at UFC 270. Ngannou has 17 wins and three losses under his belt.
Matchroom Boxing president Eddie Hearn previously said the Cameroonian could make his professional boxing debut in the summer of 2023 against Britain's Anthony Joshua.
