Derek Chisora will reverse his short-lived retirement and return to the ring in December.‘Del Boy’ hung up his gloves in April after losing his 50th professional contest to former WBC heavyweight champion Deontay Wilder at London’s O2 Arena.Chisora hasn’t set foot in the ring since losing to Wilder in AprilGettyChisora had left the door open for a rematch, but with Wilder now locked into discussions with Oleksandr Usyk, he has chosen instead to box Murat Gassiev on an IBA show.Speaking at a press conference in Istanbul on Tuesday, the 42-year-old said: “December will be me versus Gassiev.“We’re going to decide where, either in London or Manchester.“We’re going to put two belts on the line, I believe, the IBA and the one Gassiev holds. “The WBA Regular. Why not? Let’s have fun with it…“What people have to understand is that what the IBA does is unbelievable.“I believe this goes deeper than what we’re doing here right now. “I believe it’s going to get better and better. In December we’ll be fighting.”Chisora faced off with Gassiev after he retained his WBA heavyweight title against short-notice replacement Peter Kadiru in July.Pictures then emerged of Chisora sitting down for a meeting with Gassiev’s promoter, Umar Kremlev, of the IBA.Chisora faced off with Gassiev in Moscow earlier this year, and now they appear to be about to fight each otherDAZN“Derek said he wanted to come and support the IBA because he’s happy with the way IBA is organising tournaments,” Kremlev said. “And we promised him a bout. So we are going to organise a bout for Derek in England. “Our doors are always open to anyone, and we are ready to organise top-level bouts in any country.”Murat Gassiev’s response to a fight against Derek ChisoraGassiev spoke to talkSPORT.com earlier today after learning that his status as the sole WBA heavyweight champion would be superseded by a ‘super’ title fight between Anthony Joshua and Tyson Fury.During the interview, he was asked whether a fight with Chisora would be possible for his next outing.Chisora is 42 years old and has had a very punishing 50-fight careerGettyHe responded: “I don’t know really. I saw Derek a couple of times.“I met him in Dubai after the [Kubrat] Pulev fight and in Moscow after the Kadiru fight.“He is a great fighter, a little bit old, and he has a lot of very hard fights.“But he’s still very strong, both mentally and in his heart. He has the heart of a warrior, and I have a lot of respect for him. “I don’t know if it is possible, as he is not in the WBA ratings right now, so maybe I don’t fight with Derek.“But everything changes very fast, and we need to be ready for anything.”Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.
