Georges St. Pierre vs Nick Diaz in the works for UFC 158 in Montreal on March 16

Ultimate Fighting Championship (UFC) President Dana White today (Dec. 12, 2012) confirmed that bout agreements have been fired off to Welterweight champion Georges St. Pierre and Nick Diaz, but warned that the deal "isn't done yet" because signatures from both fighters are still outstanding.

MMAFighting.com provided the update this afternoon, revealing that world's leading mixed martial arts (MMA) promotion has targeted UFC 158 as the likely pay-per-view (PPV) event, which is currently slated to take place on March 16, 2013, at the Bell Centre in Montreal, Quebec, Canada.

Over the weekend, Cesar Gracie -- Diaz's trainer, mentor and manager -- revealed that he was "blindsided" when he learned through MMA media that St. Pierre had requested a fight with Diaz rather than compete in a much-ballyhooed "super fight" against Middleweight champion Anderson Silva. But, perhaps he was unaware that Diaz is an unexplainable phenomenon in Canada, with fight fans north of the United States border clamoring for the Stockton, Calif., scrapper to challenge their patron saint.

Remember, too, that "Rush" feels that he has "unfinished business" to tend to with Diaz, making the Silva fight, in his mind, a bit premature and a showdown with the most deserving number one 170-pound contender, Johny Hendricks, something that can wait.

St. Pierre is coming off a unanimous decision win over Carlos Condit at UFC 154 last month, returning from an 18-month layoff in triumphant fashion to make his Welterweight title whole once again. Diaz, meanwhile, has been serving out a 12-month suspension that was handed down by the Nevada State Athletic Commission (NSAC) in Feb. 2012 for having marijuana metabolites in his system after a controversial loss to the aforementioned Condit.

For a refresher course on the "unfinished business" between St. Pierre and Diaz, as well as Diaz's current suspension situation, I encourage you to get up to speed by reading this post.

UFC 158, which is unofficial at this time, is expected to also feature an exciting 170-pound rematch between Carlos Condit vs. Rory MacDonald. MMAmania.com will provide more on the UFC 158 fight card as it becomes available.
