David Allen battles Lucas Browne on a bumper bill at The O2, with Derek Chisora, Josh Kelly and Conor Benn also in action on Saturday night, live on Sky Sports.
'White Rhino' can take his heavyweight career to new heights with a victory over Browne, who previously claimed the WBA 'regular' title with a knockout win over Ruslan Chagaev in 2016.
The Australian has recorded three successive victories since suffering his sole defeat at the hands of Dillian Whyte, a knockout loss at the same venue in March last year.
But Allen insists he can withstand anything 'Big Daddy' can throw at him after weeks of preparation with former world champion Darren Barker.
A domestic clash against the likes of David Price or Derek Chisora could lie ahead for Allen, if he can overcome Browne in a potentially explosive encounter.
On the undercard, fellow heavyweight Chisora collides with the dangerous Senad Gashi, while exciting contenders Josh Kelly and Conor Benn return to the ring, and Joe Cordina takes on Andy Townend for the British and Commonwealth lightweight titles.
