RIYADH, Saudi Arabia - Now that Canelo Alvarez is past William Scull, the long-anticipated showdown with Terence Crawford is on.

Crawford stepped into the ring to face off with Canelo as Turki Alalshikh announced that the pair will meet for Alvarez’s Ring Magazine super middleweight championship on Sept. 12 at Las Vegas’ Allegiant Stadium.

Alalshikh later revealed on social media that the Canelo-Crawford super fight will be the first TKO Boxing event promoted by himself and UFC president Dana White.

The TV platform for the fight will be announced later, Alalshikh said.

Alalshikh and White unveiled plans for TKO’s boxing venture last month in New York. TKO was formed when WWE and UFC joined forces to form a publicly traded company. Nick Khan, the president of WWE, was a driving force in boxing for years.

He managed Hall of Famers James Toney and Manny Pacquiao and negotiated Top Rank’s media rights deal with ESPN as the co-head of CAA’s TV department.

Canelo-Crawford will be the third Riyadh Season event outside the Kingdom following Crawford-Israil Madrimov in Los Angeles and Anthony Joshua-Daniel Dubois in London last year.
