Frank Mir vs. Cheick Kongo to Headline UFC 105?

Fighters Only is reporting that Mir/Kongo will be the headliner of UFC 105:

Cheick Kongo and Frank Mir could find themselves headlining UFC 105 in November, a source close to the French heavyweight tells Fighters Only.
The two are due to fight at UFC 107 in December, but the match may be brought forward to fill the spot at the top of the 105 card.

To be honest this is far from a solid main event. Mir is coming off a fight where he was demolished by Brock Lesnar while Kongo was drummed on for three rounds by Cain Velasquez. It’s generally best practice to avoid main eventing two guys coming off of brutal losses, but the UFC is handcuffed by the lack of potential main events right now and they have to get something in place so they can start promotion.
We’ll have updates as they develop.
