Kell Brook and Katie Taylor have been added to the undercard of Dillian Whyte's fight with Joseph Parker on July 28.
The 32-year-old Brook's recent switch to light-middleweight will continue against the little-known Canadian Brandon Cook at London's 02 Arena.
Ireland's Taylor, who unified the IBF and WBA lightweight titles in her past fight, meets mandatory challenger Kimberly Connor, 37, from America.
Confirmation of Taylor's return to the ring was announced just a week after her father Pete was shot at the Bray Boxing Club in Ireland. He is recovering at St Vincent's hospital in Dublin.
