Olympic champion James DeGale will attempt to get his professional career back on track with a European title fight in September.
DeGale lost his unbeaten record - and his British super-middleweight title - to long-standing rival George Groves in May.
He will now try to bounce back by challenging European champion Piotr Wilczewski.
"Challenging for the European title is a fantastic opportunity to get myself back in the big picture in my first fight back," said DeGale.
"I've been hard in training since my last fight and I'm ready to box tomorrow if I need to, come September I'll be in great shape.
"The fight with Groves is in the past, I still believe I beat him, but I'm a positive person and now I'm focused on the future and a win will put me in a great position for a world title."
DeGale is hoping that his promoter Frank Warren can plot him a path to a world championship, just as he did for current world champ Amir Khan when his career suffered a setback when he was knocked out in the first round by Breidis Prescott.
He added: "My promoter Frank Warren has done a great job in getting me home advantage for this title shot and now I've got to go out there, do the business and win it in style.
"In fact, I'm about to sign a new three-year deal with Frank and I'm really happy that he will continue to build my career as he has done since I turned professional.
"He brought Amir Khan back from a devastating knockout loss to a world title in only three fights so I know that he can do it for me."
Wilczewski has lost only once in 30 fights and is currently ranked number three in the world by the WBO.
Warren said: "This is a make or break fight for James. He's got a big opportunity in front of him against Wilczewski and now has to go out there a deliver the goods and show the fans what he can do."
An exact date and venue for the fight has yet to be announced.
