Arslanbek Makhmudov suddenly finds himself without a confirmed opponent for his next fight.

BoxingScene.com has confirmed that a new foe awaits the unbeaten heavyweight contender, who will headline a December 16 show from Centre Gervais Auto in Shawinigan, Canada. Makhmudov was originally due to face Nigeria’s Raphael Akpejiori, who—according to a breaking news report from Canada-based network TVA Sports—will instead take a regional title fight in his home country.

The original headliner was an intriguing pairing of undefeated heavyweights on the rise.

Makhmudov (15-0, 14KOs) is coming off a ten-round decision win over former title challenger Carlos Takam on September 10 in Montreal. The feat marked the first distance for the 33-year-old Russian heavyweight now based out of Montreal, who’d previously stopped every opponent he’d faced and none lasting beyond the seventh round.

The 6’5½“ Makhmudov was looking at a rare size disadvantage prior to the switch.

Akpejiori (14-0, 13KOs) was also forced to settle for a decision win for the first time in his most recent outing, an eight-round shutout of Terrell Jamal Woods on June 11 in Atlanta. The 6’8” Nigerian—now based out of Miami—previously scored thirteen straight knockouts, all in two rounds or less.

A solid two-way test appeared to be in store, only for EOTTM having to head in a different direction due to circumstances beyond the company’s control.  

“In complete transparency, for me, it will not happen”, Estephan insisted to TVA Sports. "It was a surprise because a contract was signed, but it seems that Raphael and his team were discussing at the same time for a fight involving a belt in Nigeria.”

The new opponent for Makhmudov is expected to be announced in the coming days.

The rest of the show remains intact, including a heavyweight crossroads bout between Quebec’s Simon Kean (21-1, 20KOs) and former title challenger Eric Molina (29-8, 21KOs).

Fringe middleweight contender Steven Butler (31-3-1, 26KOs) faces Joshua Conley (17-4-1, 11KOs) in a scheduled ten-round bout. A more significant pairing pits unbeaten Mary Spencer (7-0, 5KOs) and former four-time title challenger Femke Hermans (13-4, 5KOs) in a ten-round junior middleweight bout.

Spencer was recently named as the number-one and mandatory contender for the WBC junior middleweight title held by lineal/WBC/IBF/WBO champ Natasha Jonas (13-2-1, 8KOs).

Makhmudov holds the WBC’s Silver title, though EOTTM was unsuccessful in getting him to advance in the rankings. With a win on December 16, he will then have to next face Kazakhstan’s Zhan Kossobutskiy (19-0, 18KOs).
