That deal was announced in June. Despite not coming to terms with Warren's promotional company, the Joyce bout remained on the table and will now go down in just seven weeks' time.
"It came down to the wire. Everyone was still trying to get concessions and make changes at the last minute, so it was actually on a knife edge," Higgins told the Herald of the bout finally being confirmed.
"Yesterday it could have easily fallen apart and not happened at all, so in a way it's a relief it's on because Joseph has been patiently waiting since he beat Chisora the second time for his next outing. But it's such a high-stakes game that the contracts have to be all in order and have to be right at this level, otherwise you can sell ourself down the river.
"The money has to be right; the number of fights has to be right. A lot of these contracts, especially the old-time promoters, are designed to sort of kidnap the fighter for life – for want of a better word – with clauses and options for future rights on eventualities, and a novice boxer, without knowing it, might sign something they then can't get out of.
"For us it was important to have a clean fight night contract that we can then look at renewal or otherwise. In the end we're happy to be aligned with Boxxer, Ben Shalom and British Sky, and this particular fight is going to be with Queensbury on [UK broadcaster] BT because the deal was done between them. We got there, and the fight itself is very interesting; it's a genuine 50/50 match up."
Parker is currently in the UK where he will remain for the rest of his camp, again training out of Tyson Fury's facilities in Morecambe with head coach Andy Lee, who has brought improvements out of the former WBO heavyweight champion since they started working together in early 2021.
A win over Joyce and Parker will take over the 36-year-old Brit's position as mandatory challenger for the WBO heavyweight title, which would be against the winner of the rematch between reigning unified champion Oleksandr Usyk and former champ Anthony Joshua. That rematch is scheduled for later this month in Jeddah.
