Breazeale, like Joshua, competed in the 2012 Olympic games, where Joshua claimed the gold medal.
Both fighters are also undefeated. However, unlike Joshua, Breazeale made tough work of his last opponent, Amir Mansour, tasting the canvas and losing every round before Mansour was forced quit on his stool.
“I can’t tell you how excited I am to fight again, especially at The O2, which I have made my fortress,” said, Joshua. “My coaches have watched Breazeale for a long time, and they knew he was going to be a player in the division, and now we get the chance to go war on June 25. It’s sure to be explosive, both of us like to let our hands go and score knockouts, we are both undefeated, and both have Olympic pedigree.
“I am looking to get passed Breazeale in style and continue moving towards the unification fight everybody is waiting for. I’m looking forward to being part of a stacked night of boxing and defending my title in style.”
Joshua’s first defence of his world title will be backed up by a cracking undercard with the pick of the fights seeing George Groves square off against Martin Murray.
“This is a fight I’ve wanted for a while, and I’m delighted it’s made,” said Murray. “I’ve had some huge profile fights all over the world in Golovkin, Martinez and Abraham but never had the big one in the UK. This is a fight that British fight fans can really get their teeth into, and I’m looking forward to getting the win and moving on to challenging for the World title later in the year.”
“I’m very excited to be defending my WBA International belt against Martin Murray back at the O2,” said Groves.
“I’ve had two great performances this year, both in London and the latest one back at The O2. It’s always a happy hunting ground for me.
“Martin is the perfect fight for me at this stage. He’s a seasoned campaigner, who’s boxed at the highest level for quite some time. He is a world level opponent, and I’ll have to be fully focused and prepared to beat him.
“A win against Murray on the biggest stage, will open a lot of doors and bring me a step closer to achieving my goal of becoming world champion. I’m fully expecting it to be a war; I can’t wait.”
