Adrien Broner's super-lightweight showdown with Mikey Garcia will be shown live on Sky Sports.
Both American stars have won world titles in a number of weight divisions, but reputations rather than belts are at stake when the highly-rated Garcia battles Broner, one of the sport's most controversial characters.
Garcia is moving up in weight after taking the WBC lightweight title with an explosive knockout of Dejan Zlaticanin in January, while Broner ended a spell of inactivity with a points victory over Adrian Granados the following month.
Adam Smith, head of Sky Sports Boxing, said: "We are delighted to be showing this sizzling summer match-up live on Sky Sports. Mikey Garcia is fast becoming a boxing superstar.
"His ring intelligence and incredible power reminds me a little of the great Mexicans Marco Antonio Barrera and Juan Manuel Marquez.
"A three-weight king, the classy Californian puts his unbeaten mantle on the line against the brilliantly talented but often wayward four-division champion Adrien Broner - what a fight this is!"
