Fight updates: Povetkin v Wach; Broner v Allakhverdiev; Briggs v Marrone

Povetkin will defend his WBC silver belt against the giant Pole before opening up negotiations with current champion Wilder as the stipulated mandatory challenger.

On October 3, Adrien Broner will finally be taking much-needed advice and concentrating on winning a world title at super lightweight when the American faces former champion Khabib Allakhverdiev for the vacant WBA title.

‘The Problem’ is aiming to erase the memory of his second career loss against Shawn Porter earlier this year and in the process become a four-weight world title holder against the Russian.

Allakhverdiev, 32, lost his WBA belt to Jessie Vargas last year in just his second defence, but now gets an immediate shot at redemption on the soon-to-be announced Premier Boxing Champions bill.

Finally, Shannon Briggs will oppose Michael Marrone on September 5 in Hollywood, California as the former WBO heavyweight title holder looks to continue on his path to sharing the ring with Wladimir Klitschko.

The 43 year-old, who currently boasts 35 first round knockouts, will battle the 29 year-old ex-cruiserweight at the Seminole Hard Rock Hotel and is already a heavy favourite to add another early stoppage to his record.
