Dana White hinted at the start of the UFC 137 post-fight press conference that he had a big announcement that he was waiting to make once Nick Diaz was able to take his seat on the podium. It was possibly the best fight of Nick's career, working B.J. Penn over with punches to the head and body. Penn ultimately retired. 

Dana has made GSP vs Nick Diaz official. It is rumored that St. Pierre begged the UFC President for the fight following Nick's antics after the fight. In the post fight speech Diaz had some choice words for the UFC welterweight champion. The fight is official for the Superbowl Weekend card. 

Bloody Elbow will have more in the coming days on what this fight means for the UFC and the welterweight division.
