Los Angeles resident Werdum (23-7-1) is the former champion currently ranked the third best heavyweight in the world and is determined to earn a rematch with the man who relieved him of the title, Stipe Miocic.

Standing in the way of Brazil's Werdum is Russian Volkov (29-6), who is undefeated in his last five bouts and cemented his burgeoning reputation with a knockout of Stefan Struve in the Netherlands in Sept. 2017.

Elsewhere on the card at The O2, Jimi Manuwa faces Jan Blackhowicz in the light-heavyweight division, Leon Edwards takes on Peter Sobotta at welterweight and heavyweight Mark Godbeer will enjoy home support in competing with Dmitriy Sosnovskiy.

The UFC will be making its 10th visit to London.
