Who is on the undercard?

There are some big names lower down the order on fight night, with George Groves, Chris Eubank Jr. and Anthony Agogo among the protagonists.

Dillian Whyte, beaten by Joshua back in December, is also down for a heavyweight clash against Ivica Bacurin. Here is our boxing correspondent Gareth A Davies' verdict on the fights:

George Groves vs Martin Murray

Groves defends his WBA International supermiddlewight title against teak-tough St Helens warrior Murray. Groves has fought three times for a world crown, Murray four times, three of those at middleweight before moving up to the 12st division. Groves had two high-profile contests against Carl Froch, before losing on a split decision in Las Vegas in a tilt at the WBC title held by Badou Jack. The 'International' WBA belt is a stepping-stone title but the winner of this pick 'em contest will likely once more challenge for world glory, with the WBA gong held by decorated German Felix Sturm. It could come down to desire and who has the most left in the tank.

Gareth A Davies verdict: Groves to win on points or by late stoppage.

Chris Eubank Jr vs Tom Doran

Chris Eubank Jr defends his British Middleweight title against unbeaten Welshman Tom Doran and is already being lined up for a fight with world middleweight No 1 Gennady Golovkin. This is Eubank's first contest since the night since he won the belt from Nick Blackwell, who was placed into an induced coma after their brutal battle. Eubank Jr's desire to face fearsome unbeaten Kazakh puncher Golovkin, triple belt holder and the world No1 at middleweight, is close to becoming a reality according to promoter Eddie Hearn, who said yesterday that talks for Eubank-Golovkin are almost complete for the 26-year-old, who has won 22 of his 23 professional fights. According to Hearn, WBA, WBC, IBF and IBO champion Golovkin and Eubank Jr. just need to agree to the venue before arrangements are worked on to stage the contest in September. Eubank must not take his eye of the middleweight prize, but should have too much for Doran.

Gareth A Davies verdict: Eubank to win inside five rounds.
