TERENCE CRAWFORD and Viktor Postol have signed for a highly-anticipated super-lightweight unification fight on July 23 at the MGM Grand in Las Vegas.

Crawford, WBO champion, will meet WBC belt holder Postol on HBO pay-per-view in America, the first PPV fight for either man.

Postol became the division leader last year when he stopped Lucas Matthysse in 10 rounds to claim the vacant WBC bauble while Crawford, widely considered one of the best fighters on the planet, will be making the third defence of his title.

The Omaha native, who also won world honours at lightweight, has been tipped for stardom and his fight with Postol will determine who reigns supreme at 140lbs.

The pair will meet at a press conference next week to officially announce the fight and provide details of the undercard.
