UFC president Dana White is trying to book a Welterweight title showdown between Nick Diaz and Georges St-Pierre in Montreal for UFC 158 in March, according to Ariel Helwani of SB Nation's own MMA Fighting blog.
White had been pushing for what could be an epic St-Pierre vs. Anderson Silva fight, but has reportedly shifted his focus to getting Diaz and GSP in the octagon.
The Stockton-born Diaz lost his last fight, a five-round unanimous decision to Carlos Condit, at UFC 143 in February. Following the loss, Diaz was suspended for a year by the Nevada State Athletic Commission for testing positive for marijuana metabolites. His suspension will come to an end on Feb. 4, 2013.
A Diaz vs. GSP fight had originally been slated for UFC 137, but Diaz missed a press event and was demoted to the co-main event against B.J. Penn. The UFC attempted to pair the two fighters again in UFC 143, but GSP was injured, so Diaz fought Condit. GSP defeated Condit in UFC 154, increasing the need for a showdown between him and Diaz.
