This past Saturday night in Manchester, heavyweight contender Derek Chisora once again lived up to his nickname as he went to war with former WBO world champion Joseph Parker.

Back in May, Chisora dropped Parker in the opening seconds of the first round and eventually fell short with a twelve round split decision loss.

In the rematch, Chisora was dropped three times and took a lot of punishment in a twelve round decision loss. It was the twelfth defeat of Chisora's long career.

Over the years, Chisora took some very tough defeats at the hands of Tyson Fury (twice), Dillian Whyte (twice) and David Haye.

However, there were several fights where Chisora was arguably viewed as the rightful decision winner by most observers - against Robert Helenius, the first bout with Whyte, and even the close bout with Kubrat Pulev.

After the loss, the 37-year-old Chisora rejected the idea of retirement by stating "F--- retirement. I’ll be back in the summer b!tch."

Parker, 29, has a lot of respect for the British veteran and would rather see him walk off into the sunset.

"Derek always comes for war, he was one tough guy and never stopped coming forward until the end. I felt a lot stronger. It was important to start strong and not be negative from the beginning. You can see there are improvements to be made," Parker said.

"Derek Chisora is a credit to the sport of boxing. The crowd went mental when he walked out. They just want to support him. Personally I'd like to see him walk away. He has given boxing everything, but that's his decision."
