This weekend, Alistair Overeem and Alexander Volkov will square off, with the winner set to inch closer to one of the most exclusive clubs in MMA history.
First and foremost, of course, the winner of the UFC Fight Night 184 headliner will be on the short list of contenders for the Ultimate Fighting Championship heavyweight title, with the chance to join the 16 men who have left the Octagon with that belt. And if either one manages to pull that off, they will join an even more select group: fighters who have won heavyweight titles in multiple major promotions.
