The junior welterweight matchup featuring former IBF and WBA beltholder Amir Khan and newly-crowned WBC titlewinner Danny Garcia will take place at the Mandalay Bay Hotel in Las Vegas on July 14 on HBO, Golden Boy CEO Richard Schaefer informed RingTV.com on Wednesday.

“I made the deal this morning for the Khan-Garcia fight to be at the Mandalay Bay on July 14,” said Schaefer.

The pairing of Khan (26-2, 18 knockouts), who is 25, and Garcia (23-0, 14 KOs), who is 24, was made after Khan’s intended opponent, Lamont Peterson (30-1-1, 15 KOs), tested positive for a banned substance.

Peterson dethroned Khan as IBF and WBA beltholder via split-decision in December, but his positive test forced the cancelation of their rematch that was slated for May 19.

In his last fight in March, Garcia dropped four-division titlewinner Erik Morales in the 11th round on the way to taking his belt by unanimous decision.

It was the third straight triumph over a current or former world titleholder for Garcia, following consecutive decisions over ex-beltholders Nate Campbell and Kendall Holt in April and October, respectively.

On the Khan-Garcia undercard, unbeaten heavyweight prospect Seth “Mayhem” Mitchell (25-0-1, 19 KOs) will pursue his 11th straight knockout against Johnathon Banks (28-1-1, 18 KOs).

Mitchell is coming off a third-round stoppage of Chazz Witherspoon last month after having scored a second-round knockout of Timur Ibragimov in December.

A longtime sparring partner for Wladimir and Vitali Klitschko, Banks has gone 8-0-1, with four stoppages, since himself being knocked out by Tomasz Adamek in February of 2009.
