Boxing legend Mike Tyson is wary of Terence Crawford moving up two weight divisions to face unified super middleweight champion Saul 'Canelo' Alvarez. It was confirmed last week that Alvarez had signed a four-fight deal with Riyadh Season with one of the bouts being against Crawford in September.

Crawford may have put some of their minds at ease though, after revealing on social media that with just over seven months to go until the fight, he is currently weighing 186lbs, over 18lbs over the super-middleweight limit.

Canelo Alvarez (62-2-2, 39 KO) and Terence Crawford have an agreement in place to fight in September 13 in Las Vegas.
