Despite featuring a PPV lineup comprised completely of heavyweights it looks like the scope of UFC 146 has gotten even larger with the announcement that the headlining tilt between Junior dos Santos and Frank Mir will be featured on a three-part UFC Primetime special documenting the final build towards the bout.

The first show will air on May 11 on FX at 11:00 PM EST after the latest episode of the Ultimate Fighter 15 with May 18 and May 25 hosting the following installments. Replays will be shown on Fuel TV.

Dos Santos will be putting his divisional belt on the line for the first time after winning in this past November. The 14-1 Brazilian will also be out to seek a semblance of revenge after Mir snapped Antonio Rodrigo Nogueira’s arm in December (who also happens to be Dos Santos’ friend/mentor/coach).

Meanwhile, Mir finds himself in a title-fight thanks to Alistair Overeem’s issues with testosterone in hopes of reclaiming the spot he once held as undisputed champion before suffering a potentially career-ending injury in a motorcycle accident.

The organization recently featured Jon Jones’ title-defense against Rashad Evans in a similar manner leading up to their fight at UFC 145. Other match-ups to get a similar treatment include Dos Santos’ quest to become #1 against Cain Velasquez as well as the memorable meeting of Carlos Condit-Nick Diaz this past February.
