Murat Gassiev stopped Yunier Dorticos on Saturday to set up a World Boxing Super Series final against Oleksandr Usyk that will have all four world titles on the line.
Defending IBF cruiserweight champion Gassiev floored Dorticos three times in the final round, winning their semi-final inside the distance and taking the WBA title in the process.
Russia's Gassiev will now face WBC and WBO champion Usyk in the tournament final in May - the winner will become the first boxer to hold every world title in the cruiserweight division.
Usyk was ringside in Russia on Saturday to watch Gassiev launch a last-gasp assault to halt Dorticos before the judges were required. A vicious left hook from Gassiev was the crucial blow.
Gassiev is now unbeaten in 26, and Olympic gold medallist Uysk is perfect after 14 pro fights.
