Promoter Eddie Hearn has claimed that Darren Barker can leave boxing in peace after the former IBF middleweight champion announced his retirement on Wednesday.

Barker, who won the title in August by beating Daniel Geale in Atlantic City, was forced to end his career at the age of 31 after injuring his hip in the defeat to Felix Sturm last month.

"After the changing room tears, a visit to the hospital for treatment to his hip and the disappointment of losing his world title, Darren's family and friends made their way back to the hotel," Hearn told Sky Sports News.

"We shared a beer and just by looking in his eyes I knew it was all over but Darren Barker was at peace, the struggle was over but he had achieved all he ever wanted.

"That night in Atlantic City was for me, as many of us, one of the greatest of my life but what makes me happier is that Darren can leave the sport in peace."

Barker won 26 of his 28 professional fights.
