Allen’s bout with Lucas Browne and Chisora’s clash with Senad Gashi are both the main events in the capital.
There are no titles on the line in those match-ups though the winners of both will put themselves in the mix for future heavyweight world championship fights.
Dereck Chisora lost on his last visit to the O2, beaten by Dillian Whyte in December.
But the Londoner is hoping to get the winning feeling back tonight.
“The O2 brings lots of great memories and disappointments but it’s part of boxing,” he said.
“One minute you’re jumping up on the ropes, the next minute laying under the ropes.
“This fight for me is a great fight for me, I’m excited for this fight, I’m looking forward to this fight. New coach, new skills, it’s going to be amazing.
“I’m motivated, I don’t travel three hours on the train, every four days because I’m not motivated.
“I want to fight, I love fighting and if he comes to fight we’ll fight. I don’t care, whatever he wants to do, we’ll do.
“Big fights are available. I think you’ve got the big four at the top but really and truly, the big four at the top don’t want to fight each other, so what can you say, us at the bottom of the scrap will just take them.”
