Joseph Parker has signed a three-fight deal with Matchroom Boxing ahead of a June 29 fight in the United States.

The former WBO heavyweight champion has taken promoter David Higgins with him after his contract with Duco Events expired.

Parker (25-2) will make his Matchroom bow on the undercard for Demetrius Andrade's WBO middleweight title defence against Maciej Sulecki in Providence, Rhode Island.

He said: "Since my contract with Duco ended, I have been a free agent.

"My team and I [have been] spending several months assessing how to best achieve my goal of not only becoming a world champion again, but unifying all of the belts to become the undisputed heavyweight champion of the world.

"Ultimately we decided that the best option was to partner with Eddie Hearn and Matchroom Boxing.

"We believe the three-fight deal that we are announcing today will be the start of a long and successful partnership."

Matchroom chief Eddie Hearn added: "If Joseph Parker performs the way we all know he can over these next three fights, he will have a strong case for some huge fights.

"Parker is a young man with a great mix of experience and ambition, and this is a really exciting signing for Matchroom."

Parker lost his WBO belt to Anthony Joshua in March 2018, before being beaten by Dillian Whyte in his next fight.
