LOS ANGELES — Keith Thurman has always talked the talk and walked the walk, but after fighting just twice in the last six years, the proclamations from “One Time” just don’t ring the same as they once used to.

At 36, Thurman (31-1, 23 KOs) is seeking an Indian summer when he takes on WBC junior middleweight champion Sebastian Fundora (23-1-1, 15 KOs) on October 25 at MGM Grand in Las Vegas to headline a PBC on Prime Video pay-per-view card.

"This is what the sport is all about. You put Thurman’s name next to anybody and I guarantee you it’s gonna be a fight you won’t wanna miss," Thurman said in a recent press conference.

"I’m about to conquer Mount Everest himself. They call him The Towering Inferno, but I’ve been in the fire. This is what I live for right here. This is the top of the sport."

"Once I get the WBC title, people won’t have a reason to say 'no' to a Keith Thurman fight. I’ve been waiting through the setbacks. With the truly great champions, you can’t stop them from becoming champion once again."

After beating Robert Guerrero, Luis Collazo, Shawn Porter and Danny Garcia in a 24-month stretch from 2015-17 to become a unified welterweight champion along the way, Thurman was hit with a rash of injuries and inactivity, fighting just four times since then.

His only loss against Manny Pacquiao was July 2019, sandwiched between decision victories against Josesito Lopez and Mario Barrios. Thurman made his 154-pound debut in March with a third-round stoppage of Brock Jarvis in his native Australia.

Fundora however, is a different kind of beast. Thurman knows it.

"This is gonna be an action-packed fight," he said. "This is a beautiful opportunity to step up. You have to see it to believe it, and I truly believe it’s gonna be timber on October 25.

"Everything that’s happened in the past is water under the bridge. All you can do today is put your best foot forward. I’ve been through so much throughout my career. But here I am, right here right now, back where I belong.

"I guess you can call me the OG, or whatever you want. But I’m here today because of the love I have in my heart for boxing. I love making people love boxing. That’s what it’s all about. That’s what big fights are all about."
