Underdog Crawford chases history

American aiming to shock world, Alvarez

- 

Saul “Canelo” Alvarez stands in the way of Terence Crawford's bid for boxing history today (tomorrow morning, Thai time) when they clash in Las Vegas for Alvarez’s undisputed super middleweight world title.

Crawford, a four-division champion, is jumping up two weight divisions in a bid to become the first male boxer to become an undisputed champion in three different categories.

Unbeaten with a record of 41-0 with 31 knockouts, Crawford previously claimed all four belts on offer at super lightweight and welterweight.

But the 37-year-old American will step into the ring at Allegiant Stadium, home of the NFL's Las Vegas Raiders, an underdog against Mexican great Alvarez.
