Kell Brook will continue his quest for a super-welterweight world title in July after being named on the under-card for Dillian Whyte's heavyweight bout with Joseph Parker.
The Sheffield-born fighter will face Brandon Cook in a world title eliminator at the O2 Arena in what will be his second bout at super-welterweight.
Brook stepped up in weight after losing his IBF world welterweight title to Errol Spence Jr. in May 2017, securing a second-round victory over Sergey Rabchenko in March.
July's fight sees him go toe-to-toe with Canadian Cook, the 32-year-old coming off the back of successive knockouts against Hector Carlos Santana and Miguel Angel Suarez.
Brook is joined on the card by 2012 Olympic lightweight champion Katie Taylor, the Irish boxer looking to extend her unbeaten professional record to 10 fights.
Taylor's IBF and WBA straps will be on the line against Kimberley Connor – the IBF's mandatory challenger.
Nigel Benn's son Conor will also fight in London on July 28, meeting Cedrick Peynaud for the second time after previously beating him in December.
