The 33-year-old veteran welterweight and former champion recently doubled down on remarks he made to BoxingScene.com earlier this summer regarding his status in the sport.

Thurman (30-1, 22 KOs) reiterated that point during a recent Showtime broadcast of the Omar Figueroa Jr.-Sergey Lipinets junior welterweight bout in Hollywood, Florida.

“Man, Keith ‘One Time’ Thurman is not the gatekeeper, ok?” Thurman said. “And if you wanna act like I’m a gatekeeper, then you need to understand that that gate is welded shut. And I will school you just like I schooled Mario Barrios. I’m not those past opponents. I'm a veteran. I’m a fine wine. You can only get me at a certain high level restaurants, baby.”

“This is not McDonalds. But you can still have it your way if I see a contract, I’ll sign the dotted line.”

Thurman returned from a nearly three-year layoff in February to defeat San Antonio’s Barrios by 12-round unanimous decision at the Michelob Ultra Arena in Las Vegas. Altogether, he has only fought three times in nearly six years.

Although he does not have a fight publicly lined up currently, Thurman recently indicated that he believes he might be a shoo-in for facing either Errol Spence Jr. or Terence Crawford should a Spence-Crawford welterweight full unification fight fail to materialize.

“Come on,” Thurman told FightHubTV. “[Spence and Crawford are] having [negotiations] problems right now. I don’t have a fight right now. Come on. You don’t think I’m the fall guy? Because I think I’m the fall guy.”
