EVEN a two-week extension after the original April 12 deadline wasn't enough to complete terms for Sebastian Fundora's ordered WBO junior-middleweight title defence against No. 1-ranked contender Xander Zayas.

Now, their proposed 154-pound world title fight will head to a purse bid hearing next week and be streamed live, as WBO president Gustavo Olivieri seeks to achieve total transparency.

He announced as much Saturday, tweeting: "Be advised that having the parties unable to reach terms as ordered, the WBO will order purse proceedings. $200k minimum bid with 75% for Champion and 25% for Challenger. Proceedings to be conducted next week & streamed live. #NewEra"

Fundora (22-1-1, 14 KOs), is the reigning unified WBO and WBC titleholder, having successfully defended both titles with a fourth-round knockout win over Chordale Booker in last month's PBC show on March 22.

Afterwards, Fundora's promoter Sampson Lewkowicz told the media that while Zayas had been ordered by the WBO, the only option trumping him would be another unification to supersede the mandatory.

Upon hearing his name called in the ring as a prospective opponent, IBF champion Bakhram Murtazaliev (23-0, 17 KOs) revealed a willingness to box Fundora next on social media.

Six months after his third-round knockout win over Tim Tszyu, the California-based Russian's team told The Ring he's ready to return after observing Ramadan last month, though there's no update on when he'll be back.

Top Rank-backed Zayas (21-0, 13 KOs), watched Fundora's latest win ringside and joined the 27-year-old in the ring post-fight, aware that he was next in line.

The sanctioning body confirmed as much the next day, though Zayas' desire for a first faceoff was rejected by team Fundora with younger sister and undisputed flyweight champion Gabriela insisting there was no need.

"It's the only reason I'm here," Zayas told The Ring. "I wouldn't be here if I didn't know I was gonna fight him. I'm the mandatory for a reason, he wants it to happen, I do, his team and mine are on the same page, so it's all about having a nice conversation."

The last time a potential opponent stood across from Fundora promoting a future showdown, it was former unified welterweight champion Errol Spence Jr (28-1, 22 KOs).

July marks two years since his last appearance, a dominant ninth-round stoppage loss to Terence Crawford, who clinched undisputed status but has since moved up and won junior-middleweight honours last summer.

Stalled and later cancelled plans for a voluntary unified title defence against Spence contributed to Fundora's year-long absence, while Zayas has continued building experience with a trio of victories over longtime contenders at New York's Madison Square Garden Theater in the interim.

His most recent win, a ninth-round stoppage of Germany's 20-0 contender Slawa Spomer, came on the undercard of Keyshawn Davis' knockout win over Denys Berinchyk to win WBO lightweight honours February 14.

Zayas, poised for his first major title fight, has insisted he'll return in the summertime but June is proving too ambitious a return timeline now, given the limited progress in negotiations.

As reported by BoxingScene, fair compensation and location have proven stumbling blocks to getting a deal done. Now, whoever is willing to bid the highest will have control over the latter.
