UFC 143 nightmare: St-Pierre injures his knee, Diaz and Condit to battle for interim title

UFC president Dana White and company got the bad news this afternoon: Georges St-Pierre is sidelined for an extended period of time and will miss UFC 143 in early February.

According to White twitter account, the UFC's welterweight champ suffered a knee injury.

Nick Diaz, originally scheduled to face GSP, will now battle Carlos Condit for a 170-pound interim title belt.

Apparently, one fan doesn't understand what an "interim title" fight means and lashed out at White. The UFC president handled it about the best way you can when you're engaged by an idiot.

Why an interim belt? By the time St-Pierre returns at the end of 2012, he'll have been sidelined for over 21 months. It's unknown whether Condit's original opponent at UFC 143, Josh Koscheck will remain on the card.
