Earlier in the night, Bilal Fawaz became British and Commonwealth light-middleweight champion by dethroning Ishmael Davis in a close contest.
Davis, 30, started well and landed the more crisp and cleaner punches with Fawaz guilty of too much showboating and theatrics.
But Fawaz, 37, upped his punch output and took advantage in the second half as Davis tired.
The judges scored it 114-114, 115-113 and 115-114.
Nigerian-born Fawaz adds the British and Commonwealth titles to his collection, though he continues the fight for a British passport and is currently not able to fight or travel abroad.
Fawaz, who was trafficked to the UK as a teenager and after escaping a traumatic beginning to life, is now married and a father of two children, as well as working as an Uber driver.
“I know I’m 37 years old and I don’t have much time. If I don’t capitalise on what I have now, my dream will slip away. This is just the beginning, I am ready. I want it all,” he said.
“It’s sensational. It’s overwhelming.”
“I’m not a domestic fighter,” he said. “It’s just that nobody gave me a chance. Eddie [Hearn] gave me a chance and I’ve proved him right ever since.
“Now I need to make some money and feed my family.”
Without a passport, Fawaz cannot travel abroad to accept any world title opportunities outside of the UK.
“Get this man a passport,” promoter Eddie Hearn added.
Also on the undercard in Nottingham, Molly McCann claimed her third professional win by outpointing Beata Dudek, while teenagers Leo Atang and Tiah Mai Ayton continued their unbeaten runs.
Heavyweight Atang, 19, stopped Dan Garber inside a minute to make it five from five, and Ayton, also 19, went the distance for the first time in her fifth bout, defeating Catherine Tacone Ramos on points.
Popular heavyweight Dave Allen returned to winning ways with a first-round stoppage of Karim Berredjem. The 33-year-old from Doncaster had lost to Russian Arslanbek Makhmudov – who is scheduled to face Tyson Fury in April – in his last outing.
