Terence Crawford said he is embracing the magnitude of his upcoming showdown with Canelo Alvarez on Saturday in Las Vegas, calling it the biggest fight in boxing in "probably a decade" as he bids to become the first male boxer to be undisputed in three weight classes.

Crawford, who faces Alvarez for the super middleweight title, said his preparation has remained consistent despite having to move up two weight classes to challenge the Mexican superstar in a bout that will be streamed live on Netflix.

"Same song, just a little higher tone," he said in an interview on Tuesday.
