DeGale and Groves headline Excel boxing show
British and Commonwealth champion Groves will defend his title, while DeGale, beaten by Groves earlier this year will put his WBO Intercontinental belt on the line on December 9.
Opponents for both will be announced shortly.
Groves, who beat Paul Smith last Saturday, inflicted the first loss on Olympic champion DeGale's pro career in a close and controversial points win in May at the O2 arena. The pair are on a collision course for a third meeting, having also clashed in the amateur ranks.
DeGale won the European and WBO Intercontinental titles last month in Liverpool against tough Pole Piotr Wilczewski.
Groves said: "I'm looking to put on an exciting and explosive performance for the fans as I did against Paul Smith last Saturday night at Wembley and show that I'm a true world class potential.
"DeGale can say what he wants, but he knows the job I did on Smith in two rounds was more clinical and devastating than what he did in nine rounds.
"If he wants a long career, the last thing he wants to do is fight me again, I've beat him twice, once more and that's the end of him."
DeGale said: "I won the European and WBO Intercontinental titles on my return and I'm still on course for a world title fight next year.
"I'll take Groves again at the drop of hat because I believe I beat him last time out, it was close, but I thought I won it.
"I've got my own business to see to on December 9 and I'm just focused on improving with my trainer Jim McDonnell.
"If he keeps winning and I keep winning then it's a massive fight that the public are going to want to see again."
Unbeaten Hatfield traveller Billy Joe Saunders, who claimed the Southern Area Middleweight title at Wembley last Saturday, will also feature on the Frank Warren promotion.
He said: "I won my first pro title and I'm looking forward to getting better and better with the more fights I'm having.
"Next year I'll be targeting the big three titles, the British, Commonwealth and European before I move on to the world scene."
Tickets priced at £40, £50, £80 and £100 are available frankwarren.tv.
