Armenia's Hovhannisyan (10-0, 9 KOs) will face New Zealand's Uila Mau’u (10-0, 9 KOs) on August 1 at Virgin Hotels in Las Vegas, a source with direct knowledge of the deal told The Ring. 

The heavyweight fight was originally scheduled for the ill-fated and since-scrapped July 11 show in San Francisco, which was promising to shatter outdoor attendance records by surpassing 132,000.

Hovhannisyan-Mau’u will now have a solidified slot on the undercard of the lightweight title doubleheader between Lamont Roach and William Zepeda for the vacant WBC title, and IBF champion Raymond Muratalla’s title defense against Robson Conceicao. The show is presented by Golden Boy and Premier Boxing Champions and will broadcast on DAZN and TNT as part of the second installment of "The Fight." 

"Big Gug" Hovhannisyan, ranked No. 8 by the WBA, last fought in March and scored a fifth-round stoppage win against Cesar Navarro. Hovhannisyan is coached by Hall of Fame trainer Joe Goossen and tied to Al Haymon's PBC. 

"Mayhem" Mau’u will mark the first unbeaten that Hovhannisyan, 28, has faced in his five-year career. Mau’u, 34, has not fought outside of the New Zealand boxing circuit in his three-year career.
