The Big Fight Build-Up begins on ITV4 from 6pm before The Big Fight Live broadcast gets underway on ITV Box Office at 7pm
The Super Middleweight showdown at the O2 in London will be a meeting long in the making between two boxer's who have not hidden their animosity towards each other in recent years.
DeGale and Eubank Jr's mutual dislike for each other has boiled to the surface in recent weeks, really coming to the fore in their pre-fight face to face building up to their much-anticipated contest.
A strong undercard shown exclusively live on ITV Box Office will feature a big return to the ring for Lee Selby as he takes on Omar Douglas.
The undercard will also feature a Light-Heavyweight Title Eliminator between Andre Sterling and Ricky Summers.
As well as all the above action, viewers who have purchased the DeGale v Eubank Jr package will also get bonus fight night later in the evening with coverage of the WBC Super Middleweight title fight between Anthony Dirrell and Avni Yildirim live from Minneapolis, Minnesota.
Mark Pougatch will be joined on ITV Box Office by former Super Middleweight world champion George Groves, Duke McKenzie for expert insight into this compelling contest.
Ronald McIntosh will be in the commentary position and Gabriel Clarke will be reporting from ringside.
The DeGale v Eubank Jr fight is the first major UK event of the new deal between ITV and Haymon Sports’ Premier Boxing Champions.
Late last year, ITV announced a ground-breaking new deal with Haymon Sports and Premier Boxing Champions (PBC) to bring exclusive coverage of exciting PBC world-class boxing events to ITV viewers and fight fans in the UK.
The unique collaboration is the first time that Haymon Sports and PBC has partnered with a UK broadcaster to stage boxing events regularly in the UK.
The exclusive three-year deal will guarantee a minimum of 15 televised events each year, drawing from PBC’s unrivalled group of over 160 of the best boxers in the world, which includes more than 60 current and former world champions in matches staged both in the UK and the US.
