Former two-time welterweight champion Shawn Porter has issued a warning to rising contender, Conor Benn.

Last Saturday night, Benn (18-0) stopped the usually durable Samuel Vargas in a single round. 

After the fight, the unbeaten boxer called out several names - including Amir Khan, Kell Brook - and Porter.

Porter firmly believes that Benn will not be able to blow through the top names at 147 like he blew through Vargas.

He feels the budding star is getting way too ahead of himself.

"When you're getting in the ring and you're blazing through guys, in a round or two, it's great," Porter told the Toe To Toe Podcast on Sky Sports.

"It looks phenomenal, but you really don't know. You can use that and say, 'I'm just going to blow through those guys', but nobody blows through Shawn Porter, nobody blows through Kell Brook, nobody blows through Errol Spence Jr. When that doesn't happen, you need to know that you've got some other tools in your tool box, and you can go to those things to weather whatever storm that we're going to bring you.

"That's what I say when Nigel Benn says, 'my son is ready for Shawn Porter, my son is ready for world championship contention'. Has he been through things yet in the ring, if he hasn't grown enough yet in the boxing ring as a professional? He certainly did not do it as an amateur, like Vergil Ortiz, Jaron Ennis. Those guys have been through the amateur program, they know all about it. It's only a matter of time before they get to the big time."

Porter is focused on securing the biggest names in the weight class - and he doesn't see any particular reason to get in the ring with the 24-year-old Benn.

"There really isn't [a reason.] I don't think there's much to gain for me," said Porter.

"Right here in this particular situation, something that not many people understand, especially the fighters, they don't really understand the business of boxing. The business of boxing says eight years at world championship level contention does not get in the ring with five years of boxing professionally. There's no comparison there. If the phone were to ring. I don't foresee it happening, but if it were to ring, we would kind of lean with that right there."
