DeGale, who is handled by Al Haymon Stateside, agreed to a semi-final elimination tournament earlier this year that would see both collide should they come through respective contests.
Jack’s draw with Lucian Bute in April saw him retain the title, whilst DeGale overcame Rogelio Medina to seal his place opposite the Swedish-born green belt holder.
A date in November was initially stated as the target, although DeGale has now accused Jack’s advisor Leonard Ellerbe of stalling on the signing of paperwork.
Through some social media interaction, Jack told DeGale that this simply wasn’t the case and their encounter would go ahead as planned later this year.
The Briton confirmed that a venue in boxing’s capital of Las Vegas would be no problem for him and it was just a case of the two camps reaching a finalization of terms.
With only one loss each on their records, Jack and DeGale are widely regarded as the number one and two 168 pound fighters on the planet and have been on a collision course for some time.
Haymon’s Premier Boxing Champions is set to be the platform for Jack v DeGale once the t’s are crossed and i’s are dotted for what will be a mouth-watering clash.
