Win or lose, I'd like Chisora to retire - Wardley
As a fellow fighter, I do have concerns for boxers in every fight. You see people in their first 10 bouts where something dramatic can happen, or in their last 10. It's a risk no matter where you are at with your career.
With someone like Derek though, not many people are going to be able to tell him when he should stop. He's going to dictate his own time and terms. So we can have all the concerns we want about his wellbeing, but Derek will be Derek and do what he wants.

We did plenty of sparring very early on in my career. Since then, I see him around all the time because Derek is absolutely everywhere - at every show and every event. He has always been congratulatory of me, almost proud of me in a sense.
I remember when I won my British title, he was one of the first people to FaceTime me the next morning to say well done. Derek was also one of the only people, aside from my own team, who backed me going into both the Joseph Parker and Daniel Dubois fights. He's always been on my side, so I've got a lot of love and respect for him.
