The pair – who will compete for the undisputed title in the chief support - conducted themselves appropriately to build up to the richest fight in female boxing.

Taylor, 38, is an Olympic gold medallist and two-weight undisputed champion.

One of the most sought-after rematches in boxing and the richest bout in the female code will take place on Friday as Katie Taylor takes on Amanda Serrano for the title of undisputed light-welterweight champion in Texas.

Lewis, a former undisputed heavyweight champion, is backing Fury to beat his rival if he learns from his mistakes in the first fight.
