Conor Benn returns to welterweight for the first time since April 2022 to challenge WBC champion Ryan Garcia in Las Vegas.
The 29-year-old Briton is bidding for the crowning moment of his 10-year professional career at T-Mobile Arena.
Benn has won 25 of his 26 fights as a professional and would emulate his father, Nigel, by claiming a WBC title with another victory.
Garcia, 28, is making the first defence of his belt after beating Mario Barrios by decision in February.
The American has picked up 25 victories in his 28-fight career, earning 20 of those wins by knockout, while losing two, with one no-contest.
Live text commentary will begin on Sunday, 13 September at 03:00 BST on the BBC Sport website and app.
BBC Sport spoke to figures from the boxing world to get their predictions for the bout.
