Joseph Parker will have his belt and defend it, too.

The Ring has confirmed that the interim WBO heavyweight title held by the New Zealander is now at stake this weekend. Parker (35-3, 23 KOs) is set to risk his secondary strap against late-arriving Martin Bakole (21-1, 16 KOs).

They will meet in Saturday’s DAZN Pay-Per-View co-feature, live from ANB Arena in Riyadh, Saudi Arabia.

As previously reported by The Ring, Bakole is a very late replacement for Daniel Dubois (22-2, 21 KOs), The Ring’s No. 2 heavyweight contender and current IBF heavyweight titlist. Parker was previously set to challenge for Dubois’ title, but the Londoner fell ill on Thursday and was pulled from the show.

Parker is The Ring’s No. 3-rated heavyweight contender, while Bakole is No. 6. Olekesandr Usyk (23-0, 14 KOs) is The Ring champion who also holds the primary versions of the WBA, WBC and WBO titles.

Dubois-Parker originally carried the stipulation that Parker would be permitted to retain his interim WBO heavyweight title until he entered the ring. The sanctioning body would have then removed the secondary belt from circulation for the time being, as Parker was due to challenge for the primary IBF belt.

That dynamic is no longer in play without the IBF title at stake.

WBO president Gustavo Olivieri confirmed to The Ring that Parker’s bout against Bakole will be fully sanctioned. Bakole not only fits the criteria as the No. 2 ranked WBO contender, but is the highest rated available challenger.

Zhilei Zhang (27-2-1, 22 KOs)—The Ring’s No. 4 heavyweight contender—is rated No. 1 by the WBO. However, the former interim titlist is already set to face Agit Kabayel (25-0, 17 KOs)—The Ring’s No. 5 heavyweight contender—for the interim WBC strap.

Bakole was previously scheduled to face Efe Ajagba (20-1, 14 KOs), The Ring’s No. 10 heavyweight contender, in an IBF eliminator. Their bout was due to serve as part of a Ring Magazine-branded show this May at a New York City location to be determined.

Given the recent developments, the IBF was not in a position to determine next steps—if any—for its plans to fulfill its mandatory challenger slot at heavyweight.

Parker’s bout was the second on this show to take a hit during fight week.

As previously reported by The Ring, Floyd Schofield (18-0, 12 KOs) was hospitalized on Tuesday and pulled from his scheduled clash with WBC lightweight titlist Shakur Stevenson (22-0, 10 KOs). Josh Padley (15-0, 4 KOs) was cleared and approved by the British Boxing Board of Control less than 24 hours later to challenge Stevenson, The Ring’s No. 3 lightweight.

Headlining the show, The Ring and undisputed light heavyweight king Artur Beterbiev (21-0, 20 KOs) faces former WBA titlist Dmitry Bivol (23-1, 12 KOs). Their championship clash is a rematch to their Oct. 12 thriller at nearby Kingdom Arena. Beterbiev via majority decision to fully unify the 175-pound titles.

Beterbiev and Bivol are rated No. 4 and No. 5, respectively, in The Ring’s pound-for-pound top ten.
