Former unified junior featherweight titleholder Stephen Fulton Jr. will face Carlos Castro in a featherweight bout, which will headline a three-fight preliminary undercard leading into the Saul “Canelo” Alvarez-Edgar Berlanga PBC Pay-Per-View on Sept. 14 at T-Mobile Arena in Las Vegas.

The three-bout prelims featuring Fulton-Castro will be available for free to all via live stream on Amazon’s PBC on Prime Video (6 p.m. ET/3 p.m. PT), regardless of Prime membership or purchase of the Alvarez-Berlanga PPV.

The free portion of the stream will also include Roiman Villa facing Ricardo Salas in a 10-round welterweight matchup and featherweight prospect Jonathan Lopez meeting Richard Medina in an eight-rounder in the opener.

“Saturday, Sept. 14 is a stacked card that now features six champions and former champions with the addition of the former unified champion Stephen Fulton headlining PBC on Prime Video leading into the pay-per-view,’’ said Tom Brown, president of TGB Promotions, which works on PBC on its shows. “Fulton is a top pound-for-pound talent and he’s ready to remind everyone why he belongs on that list against the always-tough Carlos Castro.’’

Fulton bounce back from his first career defeat when he takes on the hard-charging contenderCastro in a 10-round featherweight clash that adds yet another intriguing showdown to a stacked night of action.

Fulton, 21-1 (8 KOs), a 30-year-old from West Philadelphia, Pennsylvania, most recently fought Naoya Inoue last July, suffering the first loss of his career. He’ll put his slick boxing skill set to the test in his featherweight debut against Castro.

“It’s been a long time coming, but I’m glad to be back in the ring,” Fulton said. “I’ve been in the gym and learning new techniques with Bozy Ennis that I can’t wait to show my fans and the boxing world. This is a tremendous event. I plan to show out on my way to becoming a two-division world champion.”

Castro, 30-2 (14 KOs), also 30, most recently took a 10-round unanimous decision against Belmar Preciado in April. A resident of Phoenix who emigrated to the U.S. from Sonora, Mexico, as a boy, Castro has fought at 126 pounds or higher in each of his past three fights – all wins. His only two career defeats have come against Brandon Figueroa at featherweight and Luis Nery at junior featherweight. 

“Fighting Fulton is going to bring the best out of me, I can promise you that,’’ Castro said. “These opportunities only come along so often. I will take advantage of it because my life has been boxing for as long as I can remember. Come Sept. 14, I will be the best entertainer of all the boxers that night.”

The main broadcast of the Alvarez-Berlanga PPV also features middleweight titleholder Erislandy Lara facing former two-division titlist Danny Garcia, former super middleweight belt holder Caleb Plant meeting Trevor McCumby for an interim 168-pound title, and former junior welterweight titleholder Rolando “Rolly’’ Romero taking on Manuel Jaimes.
