IBF welterweight champion Errol Spence (24-0, 21 KOs) is expecting to move up, eventually, to the junior middleweight division and then to the middleweight ranks.

He wants to remain at welterweight for at least another two years, as there are numerous big names at the weight.

Spence is likely on the horizon for high stakes unification with WBC champion Shawn Porter, who last month won a twelve round decision over Danny Garcia at Barclays Center in Brooklyn, New York.

Another fight being discussed for the immediate future, is a Showtime Pay-Per-View clash with four division champion Mikey Garcia, who wants to move up by twelve rounds to challenge Spence for his belt.

And the biggest fight for Spence in the future, is a showdown with WBO welterweight champion Terence Crawford.

Spence is planning to wait until his close friend, WBC junior middleweight champion Jermell Charlo, moves up to middleweight - where twin brother Jermall Charlo is already a rising force.

Spence believes his max weight will be 160-pounds, but he doesn't rule out the possibility of heading as high as the super middleweight limit of 168 - if the right world title fight presents itself.

"I’m definitely going to move up, and I feel that Jermell’s gonna move up pretty soon after he does what he has to do at 154, like after he fights [division counterpart and WBA, IBF, IBO champion] Jarrett Hurd and gets all of the belts. But I’ve still got a lot left to handle at 147 right now," Spence said to Premier Boxing Champions.

"So I won’t be moving up for probably the next two years. If there’s a money fight at 154, I’ll move up earlier. I’m thinking about going as high as 160, and if there’s a smaller guy that wins a belt at 168, then I can probably do that. But I think I’ll stay at 160."
