Japanese superstar Ryoto Murata (14-1, 11 KOs) makes the second defence of his WBA Middleweight Title against American Rob Brant (23-1, 16 KOs) in Las Vegas on Saturday 20th October.
It will be his third fight in the world’s fight capital, and potentially the toughest test so far for the London 2012 Olympic gold medallist.
Murata, 32, lost one of the most controversial decisions of recent times when he dropped a split decision to Hassan N’Dam Jikam when they contested the vacant WBA crown in May 2017.
A rematch took place five months later and Murata made no mistake, knocking out his Cameroonian-French foe in seven rounds.
He made a successful first defence in April with an eighth-round TKO of Italian veteran Emnauele Blandamura.
Brant, 28, had a successful amateur career winning national titles, but turned pro on June 2012 and won his first 21 fights.
He surprisingly entered the World Boxing Super Series, moving up Super-Middleweight, but that led to his first loss - a points setback against German Juergen Braehmer.
Brant bounced back from that gamble with a win in March, knocking out Colby Courter inside a round and will be comfortable at his natural weight against Murata.
"It is the dream of all boxers to headline in Las Vegas, and for me, this is certainly a dream come true," Murata said.
"Brant is an excellent opponent, and I will prepare my best to put on a great performance. I am only getting started as a World Champion."
Underdog Brant said: "I am very excited about my upcoming bout with Ryota Murata. This fight has been on my mind since before he fought Hassan N’Dam.
"Though I respect all of his accomplishments, I have always felt as though I have all of the tools to clearly defeat him.
"Not only has it been a life goal of mine to be a World Champion, but also to headline a card in Las Vegas at a major venue. I take none of this lightly. This means the world to me, and that will reflect."
Conlan has been busy since making his professional debut in front of a sold-out Hulu Theater at Madison Square Garden crowd on St. Patrick’s Day in 2017.
He appeared on BoxNation in June when he dominated former World Title challenger Adeilson Dos Santos, taking a clear points win on his Belfast homecoming.
Cipolletta is a former Italian Featherweight Champion, who is coming off a second-round TKO victory against Jozsef Ajtai.
