Former super-middleweight world champion Mikkel Kessler has announced he will fight again.
The 35-year-old last fought 12 months ago, losing a 12 round unanimous decision to British rival Carl Froch.
Reports claimed that Kessler, who recently became a father, was about to call time on his 16-year professional career which boasts 46 victories, 35 by knockout, with just three defeats.
However, the Dane told a press conference in Copenhagen that he will continue his career in the ring and is targeting an October or November "big fight" return.
Kessler, whose only other loses were to Andre Ward and Joe Calzaghe, also said he would like a rubber match with Froch should he defeat George Groves.
"I've thought a lot about whether I should continue my career," said Kessler. "I became a father and I have a life outside of boxing that I really appreciate. I've got a special responsibility, so it was not a decision I took lightly.
"But I still feel I have something to prove. I hate to lose! And I lost my last fight against Carl Froch. Many thought that I would quit, but I owe it to myself and my fans to finish on top. My last performance showed that I still belong at the top and I know that my fans believe in me.
"I've talked with my team, the people around me, and they are ready to support me on the journey to become world champion again.
"I still have a desire for boxing. I still love to train, and I believe that I can become a world champion again. Now that I've made the decision, it's all in. I'm ready for all the big names out there. Whether it's Ward, Golovkin or Groves, I'm ready. A third fight against Froch, why not? I'll be ready for that too.
"I'm not rusty, but it's been a while since I've boxed, so a fight in October or November would suit me best. At that point, I'd like to have a big fight.
"Like I said; it's all in now. There is no turning back and I believe that I can do it. You don't become world champion five times, if you don't believe in yourself."
Promoter Kalle Sauerland added: "Mikkel Kessler has proven that he is one of the best boxers in the world, so it's not a comeback for me.
"In my eyes, he was never finished."
