Anthony Joshua and Wladimir Klitschko clash this weekend in the biggest fight in British boxing history.

The pair will meet on April 29, exclusively live on Sky Sports Box Office in the UK and both Showtime and HBO in the States, with the vacant Super WBA heavyweight title, the vacant IBO crown and Joshua’s IBF belt at stake.

The fight, at Wembley Stadium Connected By EE, will be watched by 90,000 spectators at the home of the England national team and will be overseen by neutral officials following specific requests from both sides of the promotion.

Representatives of both camps made a request to the sanctioning bodies and the British Boxing Board of Control that the referee and all three scoring judges be neutral.

American David Fields will be the third man in the ring.

Fields, from New Jersey, has refereed more than 200 bouts over a 17-year career, including Sergey Kovalev’s decision win over Bernard Hopkins in 2014.

He is also a former sparring partner of ‘Marvellous’ Marvin Hagler and has the size and presence to stamp his authority on the blockbuster showdown should it get ugly.

Don Trella (USA), Nelson Vazquez (Puerto Rico) and Steve Weisfeld (USA) will be the judges at ringside.

All three are experienced judges who all worked on big fights recently.

Weisfeld scored Gennady Golovkin’s decision win over Danny Jacobs, awarding the Kazakh the victory by a margin of 115-112, and was also one of two judges who scored James DeGale’s January 28 Barclays Center clash with Badou Jack, for the WBC and IBF titles at super-middleweight, a draw (113-113).

Trella returns to the UK less than a month after having been one of the judges who was scoring Liam Smith’s controversial stoppage win over Liam Williams earlier this month.

He scored the fight, at the time of the stoppage, to British champion Williams by a solitary point and also scored Golovkin vs. Jacobs 115-112 in favour of the undefeated unified king, while Vazquez scored Jamie McDonnell a 116-112 winner in his questionable points win over Liborio Solis last November in Monte Carlo.
