At this time, it is unclear if he will the fight will proceed and what terms might be negotiated if so.
Robert Whittaker won't have his undisputed UFC middleweight title on the line on Saturday when he takes on Yoel Romero.
The event can remain a PPV, however, as UFC interim welterweight title contenders Rafael Dos Anjos and Colby Covington both made championship weight for their bout.
Whittaker's middleweight title is no longer on the line today after Romero failed to make weight twice yesterday.
Romero initially came in at 186lbs and was given an additional hour to get down to 185lbs for the much-anticipated rematch but he could only get as low as 185.2lbs, meaning he was ineligible to fight for the title.
"The main event is on".
In what was supposed to be his first title defence, Australia's first UFC champion will face the man he fought and beat in his last outing.
"There wouldn't be a fight", Whittaker said. "I'm refueling and getting ready for a fight". What does it matter if you are not going to make weight?
"Interesting question", CM Punk noted.
"It's very hard. We come here to fight for the title", Romero said.
Regardless of the minor amount of weight, or what really happened backstage between the Illinois Athletic Commission, Romero, his team and the UFC, this is inexcusable. "And number two, no, I would not go".
