Jamel Herring will defend his WBO super featherweight world title against Shakur Stevenson tonight in America.
The ex-Marine will return to the ring for the first time since ending Carl Frampton's boxing career with a victory back in April.
And his opponent Stevenson is considered one of the leading prospects in the division remaining undefeated at 16-0.
A tense face-off took place before the fight with Stevenson grabbing Herring's world title belt, which provoked a heated argument.
Fireworks are expected in the ring in the early hours of Sunday morning in the UK with the fight being hallmarked as a potential classic.
Muhammad Ali's grandson Nico Ali Walsh will also make his ring return in his second professional bout.

Herring: "The odds just play to my story," Herring said. "I’ve always been an underdog, not just in boxing but in life, so I don’t get into the oddsmaker thing. It doesn’t bother me at all.
"It’s not personal, it’s just business. We’re building a fight is all it means to me. I’ve heard worse and been through worse. We’re just two top competitors in the division trying to prove who is the best.
"It just feels like another elite level fight in a loaded and talented division, so we just take it one fight at a time. We put all personal feelings to the side and just go to work and do what we have to do."
Stevenson: "It means everything to me," Stevenson said. "This is my first time being able to go against a champion and being able to take a champion's belt will mean a lot to me.... and I can’t wait to hear them say, 'and the new'.
"It’s definitely not personal, just business at the end of the day. He’s not my friend. I don’t hit him up and say, 'let’s fight.'" We don’t have any conversations. I don’t talk to Jamel Herring outside of boxing.
"You’re going to see a special night, my coming out party. It’s going to be a great night, and he said he’s going to spoil the party, so let’s see if he can do it."Read More Read More
