As WBN reported through Caribe Promotions earlier this week, Rigondeaux was awaiting a formal answer from Lomachenko and Top Rank to his original challenge and now gets his wish before the end of the year.
Full details are yet to be released, although Top Rank have confirmed the fight is on as two of the best pound for pound champions in the world collide in a mouth-watering contest.
Lomachenko, a two-weight world champion in just his seventh pro outing following a stellar amateur career, was ready to move up in weight again until Rigondeaux called him out on social media.
The Ukrainian is willing to stall the move until 2018 in order to face what many believe could be his toughest test to date.
Rigondeaux, an undefeated two-time super-bantamweight title holder, has campaigned at 122 his entire career but looks likely to head up the two divsions needed to seal his defining battle.
In a previous interview with WBN, the veteran admitted he finds it tough to put on weight, which means the Cuban may well come in light at the limit on fight night.
“That is all in the past now. I am ready for Lomachenko at 126 pounds, or even at 130 if they insist on having an advantage over me,” Rigo told WBN.
“I have no problem taking a fight up to 126lb if needs be, but not even after eating at a Cuban New Year’s party will I make 130lbs.
“So, if this fight is going to happen, it needs to take place now and at a catchweight that is fair to both of us.”
It seems Rigo has been forced to compromise in order to get the opponent he wants to help him seal a pro legacy to add to his impressive amateur one.
