This fight is said to be the biggest this year.
UFC 146's lineup is getting bigger and bigger – both literally and figuratively.
Former UFC heavyweight champions Cain Velasquez (9-1 MMA, 7-1 UFC) and Frank Mir (16-5 MMA, 14-5 UFC) will meet at the May event.
The winner gets a guaranteed title shot against either champion Junior Dos Santos or Alistair Overeem, who meet in the same night's headliner.
