The big news from Monaco is a world title shot for Mike Perez after just one fight at 200 pounds as the former heavyweight challenger readies himself to challenge WBC champion Mairis Breidis in the fall.
Perez entered the tournament late on the back of just one warm-up contest but will now challenge Breidis for the green and gold belt and a place in the semi-finals of the World Boxing Super Series.
Murat Gassiev will battle Krzysztof Wlodarczyk in a predetermined fight due to IBF mandatory ties, whilst Aleksandr Usyk chose Marco Huck for his title defence.
That left a WBA title clash between Yunier Dorticos and Dmitry Kudryashov as the fourth bout, which will eventually see one fighter take home four world titles.
Mairis Breidis v Mike Perez – WBC title
Murat Gassiev v Krzysztof Wlodarczyk – IBF title
Aleksandr Usyk v Marco Huck – WBO title
Yunier Dorticos v Dmitry Kudryashov – WBA title
