Ryan Garcia announced Saturday that he is pulling out of his scheduled July 9 fight against Javier Fortuna.
Mike Coppinger of The Athletic tweeted a screenshot of Garcia's Instagram post:
Garcia cited a desire to manage his "health and wellbeing" as the reason for calling off the fight. He also wrote: "I hope to be back soon and am looking forward to stepping back into the ring when I am my healthiest self."
The Garcia vs. Fortuna clash had been scheduled to headline a card on DAZN. It has yet to be announced if there will be a replacement main event.
Garcia, 22, is one of the fastest-rising stars in the sport. He owns a perfect career record of 21-0, with 18 of those wins coming by way of knockout.
In his most recent bout, KingRy beat Luke Campbell by seventh-round technical knockout to become the interim WBC lightweight champion.
Garcia had been set to put that interim title on the line against Fortuna, who is a 31-year-old former WBA (Regular) super featherweight champion.
Fortuna is 36-2-1 with two no-contests, and he has won 25 of his fights via knockout. Fortuna had been set to enter the Garcia fight on a three-bout winning streak.
The winner of Garcia vs. Fortuna would have become a mandatory opponent for WBC lightweight champion Devin Haney, who is a perfect 25-0 in his career.
Haney is scheduled to put the WBC lightweight title on the line on May 29 when he faces Jorge Linares in Las Vegas.
