Daniel Dubois stormed the ring after Oleksandr Usyk's win over Tyson Fury to demand a rematch and "revenge" in what could be another undisputed heavyweight title matchup.
Usyk produced another superb display to beat Fury on points for the second time in 2024 and retain his WBO, WBA and WBC titles, this time scoring a unanimous decision from the judges in Riyadh.
IBF champion Dubois, who claimed a sensational knockout win over Anthony Joshua at Wembley in September, wants to avenge what he described as a "robbery" when Usyk beat him in Poland in 2023.
Usyk knocked Dubois out in the ninth round but Dubois said he had been "cheated" out of victory after flooring the Ukrainian with a body shot in the fifth round, which the referee ruled a low blow and subsequently gave him additional time to recover from.
"Usyk! I want my revenge," Dubois said as he interrupted Usyk's post-fight interview on Saturday night.
"Well done on tonight. God bless.
"I want my revenge for the robbery last time.
"Let's get it. Let's go. Where's Frank [Warren]? Make it happen!"
Dubois' decision to invade the ring after Usyk's win in such a high-profile fight was questionable in any case, but is made even more bizarre by the fact the Brit needs to first come through a tricky defence of his title against former world champion Joseph Parker on February 22.
Usyk was typically cool in the face of Dubois' antics and turned to Turki Alalshikh, the lead figure behind Saudi Arabia's position at the centre of the boxing world, asking that he make the bout.
Usyk said: "Mr Excellency, Your Excellency. Make me fight with Daniel Dubois. Thank you so much."
Asked later in his interview about the possible fight, he added: "No problem. After a rest, I am ready."
Daniel Dubois' former trainer Shane McGuigan said he would expect Usyk to beat the Brit if they were to meet again.
The 27-year-old has rebuilt his career with knockout wins over Jarrell Miller, Filip Hrgovic and Joshua since the August 2023 defeat to Usyk.
McGuigan told Sky Sports: "I feel like he had great success in that first fight. Daniel's grown a lot since that. He's got great confidence, he's come off some brilliant wins.
"But the longer that fight went on, Usyk had his number and had it well. He figured him out, he was pushing him back, caught him with little, short shots.
"And Daniel's an on-top fighter, he has to hit you and hurt you and he couldn't find the shorts.
"He got that body shot in but I just don't see him being able to change the outcome of that first fight.
"I'd see Usyk beating him again, maybe even inside the distance."
