Over two years ago, Devin Haney and Ryan Garcia birthed one of boxing’s most fierce rivalries, but both now reign as world champions in the welterweight division.

In April 2024, Garcia had been poised to challenge for Haney’s WBC super-lightweight world title, but ‘King Ry’ lost that opportunity when he weighed in three pounds over the 140lb limit.

The bout went ahead and in a shocking turn of events, the presumedly ill-prepared Garcia was dominant, flooring the champion on three occasions on route to a majority-decision victory.

Yet, the drama was not done there, as Garcia later tested positive for Ostarinewith Haney appealing the result of the fight and having it overturned to a no-contest.

Haney has since gone on to capture the WBO welterweight crown, whilst Garcia claimed the WBC world title earlier this year. Speaking on the Ring Champs YouTube channelformer welterweight undisputed champion, Terence Crawford, predicted that Haney would get the better of Garcia, if a unification rematch were to take place.

“Ryan Garcia [is] cool but he ain’t smart enough [to beat elite fighters]. It’s just that he and Devin fought each other so many times [in the amateurs]they just know each other.

“I think that all of the antics before the fight distracted Devin and caught him off guard, he took Ryan lightly.

“I do [think it would be different if they fought again] because, if you watch the fight, he was just getting hit with the same punch over and over and over.”

Garcia is set to defend his world title for the first time when he is tasked with Conor Benn on Saturday, September 12whilst Haney is still waiting to confirm an opponent for his first outing of 2026.

Hall of Famer Barry McGuigan has named one half of the main event between Ryan Garcia and Conor Benn as the “dangerman” at 147lbs.

The two welterweights will collide at Las Vegas’ T-Mobile Arena on September 12, with Garcia making a first defence of his WBC world title.

He claimed the belt by dethroning Mario Barrios with a unanimous decision victory in February, which followed his surprising points loss to Rolando Romero in May 2025.

Interestingly enough, this defeat came shortly after his year-long doping ban, which he served on account of testing positive for ostarine ahead of his majority decision victory over Devin Haney.

The result of their showdown was then ruled a no-contest, with Garcia subsequently moving up to welterweight after failing to keep below the 140lb limit.

It now seems the 27-year-old is competing at a more natural weight while Benn, who tested positive for clomifene in 2022, has not made 147lbs since his second-round finish over Chris van Heerden that same year.

Speaking with talkSPORTIrish boxing icon McGuigan suggested that this – as well as the 29-year-old’s technical flaws – could prove a major factor against Garcia.

“[Benn’s] got that genetic code from his dad, and he’s got that explosiveness and everything else. But he is predictable – you can see when he’s going to throw.

“You ask yourself: is Garcia just a little bit too sharp for him? A little bit too cute. I think Garcia’s finally found the weight he’s most suitable [for]. I think he’s a dangerman at 147[lbs].

“Maybe Conor Benn has left it a little too late to make 147[lbs] again. I think that could be his Achilles’ heel. I make Garcia a slight favourite but would never write off Conor Benn – he’s got that fighting heart.”

Benn comes off a unanimous decision victory over Regis Prograis in April, which followed his two middleweight encounters with Chris Eubank Jr last year.
