Anthony Joshua will make the first defence of his IBF world heavyweight title against Dominic Breazeale on 25 June.

Joshua, 26, lifted his first world title after dominating Charles Martin inside two rounds at the O2 Arena on 9 April. He will return to the venue next month to take on 30-year-old Breazeale, who holds a professional record of 17 wins and 0 losses.

"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.

"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, a 2012 Olympic champion, is undefeated in his 16 bouts as a professional, each of them coming via knockout. California-born Breazeale was one of three possible opponents named by Joshua's promoter Eddie Hearn in the aftermath of the victory over Martin and has welcomed the opportunity to tangle with a fellow Olympian.

"We are both 2012 Olympians, undefeated, and pack a punch," he told Boxing News 24. "The United States of America versus Great Britain. I want to go back to London and finish what I didn't in 2012. Instead of the gold medal, I want the IBF title, and I guarantee you I'm bringing it back to the United States where it belongs."
