Following the withdrawal of Junior dos Santos from UFC 215, Francis Ngannou has challenged Alistair Overeem to step in and face him.

Recently the UFC announced that dos Santos will no longer fight Ngannou as scheduled, since the former heavyweight champ has been informed of a potential anti-doping violation. The manager of dos Santos has released a statement, denying that the fighter used performance enhancing drugs.

More recently, Ngannou tweeted out the comments below:

@Alistairovereem been mentioning my name everywhere . I'm now open and free for you guy . Let do this at #ufc215
