LAS VEGAS – Josh Taylor is completely open to remaining within the 140-pound division for his next fight.

The undefeated, fully unified champion believes there remain “big fights” for him at the junior welterweight limit, which he makes “easily.” If Taylor wants to keep each of his four titles, though, he’ll almost certainly have to make a mandatory defense of his WBO belt next against England’s Jack Catterall.

The British southpaw has long been the WBO’s number one contender in the 140-pound division. Catterall also stepped aside from his overdue title shot to allow Jose Ramirez, then the WBC and WBO champion, to battle Taylor in a 12-round title unification fight Taylor won by unanimous decision Saturday night inside The Theater at Virgin Hotels Las Vegas.

“I’ve also got Catterall as well,” Taylor said during a post-fight press conference. “I might have to do that first as well. He agreed to step aside [to] let this fight happen, so if I have to do that next, I have to do that next. But if something bigger comes along, then we might have to go for that, you know?”

Catterall is undefeated (26-0, 13 KOs), but Taylor would be a significant favorite over him. Facing Catterall could present a perfect opportunity for Taylor to schedule a homecoming fight in Scotland following his historic victory versus Ramirez (26-1, 17 KOs).

The 30-year-old Taylor (18-0, 13 KOs) hasn’t fought in his home country since he defeated Russia’s Ivan Baranchyk (20-2, 13 KOs) by unanimous decision to win the IBF belt in May 2019 in the semifinals of the World Boxing Super Series’ 140-pound tournament. That bout took place at The SSE Hydro in Glasgow, where Taylor boxed four straight times in 2018 and 2019.

Taylor, a native of Prestonpans, expressed specific interest in fighting in Edinburgh, Scotland’s capital city. The IBF/WBA/WBC/WBO champion hasn’t boxed in Edinburgh in 3½ years, not since he knocked out Mexico’s Miguel Vazquez (43-10, 17 KOs) in the ninth round of their November 2017 fight at Royal Highland Centre.

Now that he is one of boxing’s biggest stars in the United Kingdom, Taylor hopes to fight either at Edinburgh Castle or Easter Road, the home soccer stadium of Edinburgh’s Scottish Premiership club Hibernian FC.

“[The Vazquez fight] was a few years ago now, so I’d love to go back home and take a big fight back to Scotland,” Taylor said. “Especially, now is the time to get that fight at Edinburgh Castle, at Easter Road. I know Easter Road are gonna be up for having me there. They’ve said it to me a few times, so I’d love to have it at Easter Road. But I’d love to fight at Edinburgh Castle. You know, I think that would just be iconic, with the castle [set] in the background.”
