Oleksandr Usyk has handed the heavyweight belts he won on Saturday back to Anthony Joshua.
In a video uploaded on Twitter, Usyk was seen telling Joshua â€œsee you soonâ€
The British-Nigerian boxer is suspected to have suffered eye socket damage.
Joshuaâ€™s promoter, Eddie Hearn, has revealed that he could not see properly after the ninth round.
By the 10th round, â€˜AJâ€™ was carrying a black and swollen eye, as Usyk continued to batter him at the Tottenham Hotspur Stadium.
The Ukrainian almost knocked him down in the final seconds, but won via unanimous decision 117-112, 116-112 and 115-113.
â€œHe will go to hospital. I donâ€™t know if he has broken his eye socket, it doesnâ€™t look great.
â€œHe said he couldnâ€™t see after the ninth round, obviously he was getting tagged a lot as well.
