UFC officials confirmed today that former Strikeforce welterweight champ Nick Diaz (26-8 MMA, 7-5 UFC) will face current UFC welterweight champion Georges St. Pierre (23-2 MMA, 17-2 UFC) in the main event of UFC 158, set for March 16th in Montreal, Quebec, Canada.

GSP and Diaz were originally scheduled to fight in October of 2011 at UFC 137, but Diaz failed to show-up for a pair of promotional appearances and was subsequently pulled off the card. However, in an odd twist, he was later placed back on the card against B.J. Penn after St. Pierre was forced to withdraw from the event with a knee injury.

GSP vs. Diaz was then planned to take place at UFC 143, but once again “Rush” was forced off the card, which allowed Carlos Condit to step in and defeat Diaz in a hotly-contested decision win and in doing so claim the UFC interim welterweight title. Diaz then tested positive for marijuana metabolites in a post-fight drug test, resulting in him being suspended by the Nevada State Athletic Commission through February 2013.

Hopefully the third time will be the charm, and the French Canadian and 209 Native can finally have their grudge-match.
