2. Alistair Overeem

3. Cain Velasquez

4. Fabricio Werdum

5. Daniel Cormier

6. Frank Mir

7. Josh Barnett

8. Antonio Silva

UFC has booked a unique attraction for UFC 146 in May, as all five main card bouts will be heavyweight contests. Half of the top ten will compete, with Junior Dos Santos vs. Alistair Overeem for the UFC heavyweight title headlining. The winner of a Frank Mir vs. Cain Velasquez on the same show will be the likely next challenger. Also on tap, Mark Hunt will have the opportunity to continue his recent surge when he faces Stefan Struve. Hunt appeared to be finished with a 5-7 MMA record just two years ago but after beating Cheick Kongo he finds himself a most improbable contender.

Light Heavyweight

1. Jon Jones

2. Rashad Evans

3. Dan Henderson

4. Mauricio “Shogun” Rua

5. Lyoto Machida

6. Gegard Mousasi
