A two-time world champion appears to have made a U-turn on a potential showdown against pound-for-pound star Canelo Alvarez.

One day, the mega-fight between Canelo Alvarez and Terence Crawford is on; the next day, it’s off. The latest update indicates there's been a significant snag.

Alvarez vs. Crawford was to take place in September at Las Vegas' Allegiant Stadium on a show organized by Riyadh Season, the entity operated by Alalshikh and Saudi Arabia's General Entertainment Authority.

Amir Khan knows what it takes to get into the ring with both Canelo Alvarez and Terence Crawford. The British star, a former world champion, spent the bulk of his illustrious career chasing the big fights and that included landing showdowns with the aforementioned boxers.
