No idea what direction Allen is trying to steer his career in. He's in an enviable position where he has a large, loyal fan base who wish him well, more to do with personality rather boxing ability mind you. Why not rebuild against English/lower British level for the next couple of years. He isn't the biggest heavyweight and Fighting the likes of whyte, Ortiz and Yoka will take years of the career for little reward.
I respect Allen but the word 'No' has been cut out of his dictionary. He takes every fight he can get. I'm afraid Yoka is too much for him.
