UFC Welterweight Champion Georges St. Pierre has suffered a knee injury and will not fight Carlos Condit at UFC 137 on Oct. 29 in Las Vegas, Nevada.

That's according to UFC President Dana White, who today tweeted the horrific news:

I just land in NYC and what do I always say!? I have to deal with bad shit everyday!! GSP is out with an injury!!! It's GSP'S knee. We will sit Carlos to wait for GSP. It's looking so far like he could be ready in a couple months. Still early to tell tho

Condit will not lose his opportunity to fight St. Pierre for the title and will instead be riding the pine, for however long, as the Canadian is in no "Rush" to commit to a return date.

In their absence, the welterweight scrap between Nick Diaz and B.J. Penn is now the new headliner, which is ironic, considering how everything transpired and yet Diaz is once again main-eventing the UFC 137 pay-per-view.

This is certainly a crippling blow to what was widely considered one of the most anticipated events of the year.
