The two big men now know the details.
The fight will determine the No. 1 contender to the UFC heavyweight strap currently wrapped around Junior dos Santos’ waist. UFC 146 will also determine who Mir or Velasquez will face for the title.
The champ will also defend his belt at UFC 146 against Alistair Overeem in the night’s main event.
Velasquez (9-1) captured the UFC title from Brock Lesnar at UFC 121 in late 2010. He was then sidelined for a year mending from shoulder surgery.
Velasquez returned to face dos Santos at the first UFC on Fox event last November in Anaheim, Calif., where JDS wasted no time ending Velasquez’s reign, knocking him out in little more than a minute.
Mir (16-5) fought a month after Velasquez’s last bout, finishing Antonio Rodrigo Nogueira for a second time with an arm-breaking Kimura.
Though Mir failed in his last two title bids, he is currently riding an impressive three-fight streak, which also includes Mirko “Cro Cop” Filipovic and Roy Nelson.
Now, one of the two former champions will get another shot at the belt.
