Regis Prograis’ power eventually was too much for Jose Zepeda on Saturday night.

Prograis became a two-time 140-pound champion by knocking out Zepeda early in the 11th round of their fight for the vacant WBC super lightweight title at Dignity Health Sports Park in Carson, California. Referee Ray Corona stopped their 12-round championship match 59 seconds into the 11th round, right after Prograis’ left hand finally sent a stubborn Zepeda to the canvas.

Prograis won the WBC 140-pound crown that Josh Taylor vacated earlier this year in the main event of a five-fight pay-per-view show.

The 33-year-old Prograis, a New Orleans native, became a 140-pound champion for the first time in three years. Prograis (28-1, 24 KOs) lost the WBA super lightweight title to Taylor by majority decision in October 2019 at O2 Arena in London and hopes to entice Taylor into a rematch.

Prograis, who boxed and slugged at times Saturday night, became the first fighter to knock out the 33-year-old Zepeda (36-3, 28 KOs, 2 NC), of La Puente, California. He also prevented Zepeda from finally becoming a world champion in the third title fight of Zepeda’s 13-year pro career.

Prograis expressed respect toward Zepeda during his post-fight interview with Raul Marquez in the ring.

“Listen, first off, before I say anything I wanna congratulate Jose Zepeda,” Prograis said. “That dude is tough, tough, tough. Bro, he came to fight. He probably gave me one of my hardest fights. I’m not even gonna lie. Like, this dude is tough. Bro, you so tough. Bro, I got so much respect for you. And you prepared me to get this belt, and to hold this belt. So, I congratulate you. All the best to you, bro. Don’t stop. I feel like you still gonna be a world champion. You good, bro. You real good. I’m not even gonna lie. You good.”

The beginning of the end came 50 seconds into the 11th round, when Prograis stunned a depleted Zepeda with a left hand. Zepeda backed toward the ropes and Prograis unloaded power punches on him.

Prograis’ overhand left sent Zepeda into the ropes and then to the seat of his trunks. Corona stopped the fight immediately after Zepeda went down.
