According to a report in The Sun, - IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua (21-0, 20 KOs) is going to sign a three-year extension with Eddie Hearn of Matchroom - worth £100 million.

Joshua, who won an Olympic gold medal in 2012, has been promoted by Matchroom since turning pro in 2013.

But his promotional agreement with Hearn is set to expire in November - and there are numerous parties making a financial play for the 29-year-old.

Last week, Hearn announced that his company signed an eight year content deal worth $1 billion with Perform Group. Matchroom will be streaming numerous events in the United States via Perform Group's streaming service DAZN.

Matchroom founder Barry Hearn is very confident that Joshua will extend his promotional pact and he outlined the reasons. He believes Matchroom has all of the advantages to reclaim Joshua for several more years.

“Anthony is an astute young man and he knows what Matchroom has to offer him when his contract runs out in November. To start with, Anthony is signed to the biggest and best promotional company in the world. We have the financial clout to make sure the big fights can go ahead at the big venues. We also have an exclusive contract with Sky Sports to screen quality boxing. There is also Sky Box Office," Barry Hearn said to the paper.

“On top of all that, Anthony is also a friend. If he went, it would be like someone in the family leaving. No one at Matchroom is putting Anthony under pressure — but I am as confident as anyone can be in boxing.”

The Hearn father-son duo is attempting to make a deal where Joshua will collide with WBC heavyweight champion Deontay Wilder (40-0, 39 KOs) in what would be the biggest fight in boxing.

If no deal is reached, Joshua would then face his mandatory challenger under the WBA and WBO, Alexander Povetkin of Russia.
