WBO welterweight champion Terence Crawford (33-0, 24 KOs) is looking forward to a future showdown with Errol Spence (24-0, 21 KOs), who holds the IBF welterweight title.

Crawford moved up to the welterweight division a few weeks ago and dominated Jeff Horn in a one-sided TKO win to capture the WBO belt at the MGM Grand in Las Vegas.

And Spence came back a week later as he demolished mandatory challenger Carlos Ocampo in the first round in Frisco, Texas.

Both Spence and Crawford are scheduled to see action in the fall.

Crawford is likely returning in mid-October. Undefeated challenger Jose Benavidez has been mentioned as a potential opponent.

Spence is returning around the same time, with opponents like Jessie Vargas being mentioned. Beyond Vargas, Spence is being lined up to fight the winner of the fall bout between Shawn Porter and Danny Garcia, who battle for the vacant WBC title.

At the moment Crawford and Spence are far apart from fighting as they continue to build their profiles - but Crawford expects them to eventually collide in the ring.

"He's considered to be one of the best welterweights... if not the best welterweight in the division - and I think I'm the best welterweight in the division... now that I stepped in the division. There can only be one king. Me and him are going to have to find out who's the king, so in the future that fight will happen. It's going to be for welterweight supremacy," Crawford told the Breakfast Club.

The biggest problem in making that fight is the promotional affiliations. Crawford is promoted by Top Rank, which has an exclusive television deal with ESPN. And Spence is aligned with Premier Boxing Champions and Showtime.

Top Rank's CEO Bob Arum, who promotes Crawford, had recently explained to BoxingScene.com that Crawford vs. Spence unification would eventually happen - but it's only possible to make that fight on pay-per-view.
