A couple of weeks ago a press release from boxing promoter Don Chargin indicated that Strikeforce welterweight champion Nick Diaz was set to fight former super-middleweight champion boxer Jeff Lacy later in the year, but today he has released another announcement confirming that Diaz has now pulled out of talks.

The news comes days after Diaz met with Dana White in Las Vegas to discuss his future, while at the weekend MMAWeekly reported that Diaz Vs UFC welterweight champion Georges St.Pierre was now on the cards.

White has since denied that this superfight has been signed, but Chargin’s comments today indicate that something big is in the works for Diaz in the MMA world.

“Nick is a good kid and a very exciting fighter. Right now he has an opportunity of a lifetime as it pertains to his MMA career,” the statement from Chargin said.

“While I don’t doubt that Nick and his team were serious about taking the big step into boxing, it only makes sense for him to finish what he started and see how far he can go in MMA before he does anything in boxing. It’s all about timing… we began these discussions over two years ago and nobody would have imagined the type of demand that there currently is for Nick as a mixed martial artist.”

In recent weeks Diaz and his manager Cesar Gracie had appeared to be adamant that Diaz would only back down from his desire to compete in boxing if the UFC stepped up and gave him a fight with St.Pierre, so all evidence continues to point towards that fight becoming a reality.

It’s a bout that would be huge not only in terms of being a ‘superfight’ that will attract a lot of fan interest and give the UFC one of the most marketable challengers in quite some time for their long-running champion, but also due to the implications it has with regards to the current barriers that exist between the UFC and Strikeforce now that Zuffa own both companies.

Update: Commenting after this latest development Dana White appears to confirm that the GSP Vs Diaz fight is being worked on, but that it could still fall through.

“We will see. There are still a lot of hurdles,” White informed MMAJunkie.
