The 25-year-old contender returns to the ring three months after his points loss to former World Champion Alexander Povetkin at The O2 in London seeking to rise back up the rankings and secure another shot at one of the top Heavyweights in the world.
“I’m delighted to return so soon after my last fight with Povetkin,” said Fury. “I feel I’ve much more to give and want to keep active and improving my game.
“After my fight I took a week off and then got straight back into training as I’ve little to celebrate and can’t think of holidays when things are not going right. I’m stronger and fitter than ever before and you will see a big difference on Saturday.
“The fans will see a hungrier fighter, and no matter what adversity comes my way I will keep pressing as I know all of the fighters out there are not above me. It’s what I’m doing wrong myself.
“There are no excuses, I’m back and ready to achieve my main ambitions in life. I hope this opportunity will put me straight back in the mix for another top fight, and Eddie and my team will be the judge of that after my fight.”
