After reports that a long-discussed bout between Saul "Canelo" Alvarez and Terence Crawford was inching toward being finalized, a new report from The Ring Magazine claims that those negotiations have fallen apart.

On Monday, Ring Magazine reported that Alvarez and Crawford had an agreement in place for a deal that would see Crawford challenge Alvarez for his unified super middleweight titles, before a subsequent Ring Magazine report two days later indicated the fight was canceled for undisclosed reasons.

Mike Tyson has criticized Terence Crawford’s decision to fight Canelo Alvarez. Crawford is chasing history by moving up to 168 pounds in order to try to become undisputed in a third weight class. That requires him to jump up two weight divisions from 154 pounds.
