Prograis-Haney, Ramirez-Espinoza live results and analysis

Devin Haney, the former lightweight undisputed champion, is moving up in weight to challenge WBC junior welterweight champion Regis Prograis Saturday night in San Francisco.

Haney (30-0, 15 KOs), relinquished his 135-pound belts in November and plans to continue his career at junior welterweight. He unified the 140-pound division by defeating George Kambosos Jr. in June 2022 and defended the belts twice, in a rematch against Kambosos in October 2022 and against Vasiliy Lomachenko last May.

Prograis (29-1, 24 KOs) has fought most of his career above 140 pounds. He won the WBC title against Jose Zepeda in November 2022 and defended the belt with a split decision win against Danielito Zorrilla in June.

“I’m going to beat the f— out of you,” Haney told Prograis during a news conference early in the week. “You’re a one-tricky pony. You do the same thing every fight.”

Prograis isn’t impressed with the power of Haney, who hasn’t scored a KO win in his past seven fights.

“You haven’t had a knockout in four years,” Prograis said. “Who have you knocked out? Nobody!”

Also on Saturday in Pembroke Pines, Florida (ESPN/ESPN+, 10 p.m. ET), Robeisy Ramirez defends his WBO featherweight title against Rafael Espinoza.

Ramirez (13-1, 8 KOs), an accomplished amateur for Cuba, has won 13 consecutive fights since losing his pro debut in August 2019. Espinoza (21-0, 18 KOs), of Guadalajara, Mexico, has won his past five fights by stoppage.
