Horn lost his World Boxing Organisation welterweight championship when he was finished inside nine rounds during a Terence Crawford masterclass in Las Vegas last weekend.

The big question now is who comes next?

Horn finds himself entrenched in an intriguing situation that has left him without a world championship belt and still fighting for the respect of many in the boxing world.

But the 30-year-old's steely resolve has not wavered and he wants to be back in the world title picture "as soon as possible".

"Another world title crack would be the dream come true again, just to hold that belt. I don't lose mine now but the title is gone. I can get it back," Horn said.

"I'm looking at possible [Jesse] Vargas and [Adrien] Broner fights and things like that so we'll just see what happens.

"You win some, you lose some. I still feel like I've got plenty more to prove and good on Crawford, he has done very well, but the loss isn't going to be the end of me."

Horn would be willing to hang up his gloves if he earns enough money to set up his family for life, adamant he won't be fighting until he is 40 and clinging on to the threads of yesterday.

Horn's promoter Dean Lonergan says that declaration makes Horn's next two fights crucial in the context of his career, because he needs to rebuild confidence but at the same time can't afford to fight "patsies".

"I’m keen to stick in the welterweight division and keen to stick with guys who will give Jeff a good challenge," Lonergan said.

"Let’s not forget who we were up against last night, it’s unlikely that many welterweights could get in there with Terence Crawford and have anything but the result we saw.

"I’ve got no doubt Jeff can match it with Keith Thurman, [Danny] Garcia, [Shawn] Porter. Don’t underestimate what you saw, what you saw is a guy who firstly, whether he fights again or not regardless of the fight, he’s going to the boxing Hall of Fame.

"I think Jeff can most certainly foot it with every other welterweight out there, because they are not Terence Crawford."

Crawford has already turned his attention to unifying the division - the same feat he achieved at junior welterweight.

He has WBA super champion Thurman, WBA regular title-holder Lucas Matthysse, IBF champion Errol Spence Jr and the vacant WBC strap in his sights.

They are all fighters on Horn's radar as well. One name that won't go away is one Lonergan is firmly against.

"One fight that appeals to me like drinking 10 cups of warm sick is Anthony Mundine," Lonergan said.

"I don’t have a lot of interest in it. While Mundine might be a big money fight, it’s not exactly going to cover Jeff’s career in glory."

Rushton is more open to a Mundine bout than Lonergan but says he would much rather continue to chase bigger fights against ranked welterweights.

He hasn't ruled out having another crack at the new WBO champion but concedes right now Crawford is the No. 1 guy in the division, and he is followed by "daylight".

"When you look at the division, to me Crawford is there and then there is a bit of a gap to the others," Rushton said.

"Everyone else below Crawford is on the table, I ideally think Crawford is on the table again but I think we need another couple of fights, at least two or maybe three fights, see where Crawford is at then and we’d love to get a rematch with him down the track."
