Both Nate Diaz and Dustin Poirier claimed Tuesday night that they're fighting in the main event of UFC 230 in a title fight for the newly-unveiled 165-pound division.

Diaz returns to action for the first time in over two years against Poirier at the annual Madison Square Garden event which takes place Nov. 3, and many expected the lightweight bout to be the co-main event of the card.

But with just over a month to go, there is yet to be a main event despite UFC president Dana White stating he's been working on one.

Welterweight champion Tyron Woodley requires hand surgery, so he will be unable to take on Colby Covington while despite Jon Jones being cleared to fight again, White said he would only return at the start of the new year, ruling out a New York return for the former light heavyweight champion.

Instead, calls have been made for Diaz and Poirier to fight in the main event, preferably for a 165-pound title. With the 15-pound gap between the lightweight and the welterweight division, many fighters such as Kevin Lee have called for a division in that weight class.

Poirier also recently proposed for the fight to be made for a title in that weight class and it looks like it may be happening as both fighters took to Twitter to share the news.

Despite their claims, however, White responded, stating it was not happening and that he was still working on a main event, according to ESPN's Brett Okamoto.

It remains to be seen what fight could be made for the main event for UFC 230 if White is still working on it, given the current unavailability of many champions.

The best course of action would be having Jones fight on the card, preferably against Alexander Gustafsson for the interim light heavyweight title.

The New York native will be eligible to fight by the end of October and both fighters have already proposed a rematch after their first meeting in 2013 which many regard as one of the greatest title fights in UFC history that saw Jones win via unanimous decision.

UFC 230 tickets will go on sale this Friday and a main event is expected to be announced by then.
