Ahead of his scheduled bout with undisputed middleweight champion Robert Whittaker at UFC 225 on Saturday in Chicago, Romero once again failed to make the required 185 pounds during the early weigh-in on Friday.
The 41-year-old Cuban's recent struggles come on the heels of an eight-fight win streak that began with an impressive opening-round KO of Clifford Starks in his promotional debut at UFC on Fox 7 in January 2013. Romero was granted two hours to see if he could lose that last pound but did not show up until 10 minutes before the cut-off point.
"I missed weight but the situation is very complicated", Romero said. Romero won that bout via a knockout, and although he wasn't awarded a belt, he immediately was given a title shot despite his weight cutting issues.
Now recovered from a staph infection and a nasty case of chickenpox, Whittaker is ready to get back in the Octagon with the "Soldier of God".
Whittaker said: "I have a great team and a great staff".
While Whittaker admits it's a "pain in the arse" to face the same man in consecutive fights, he is not one to pick and choose his opponents. "I'm refueling and getting ready for a fight".
"I think you do have to get on with it and move on, that's the inevitable outcome", Whittaker told ESPN. As it is still the main event, it will remain a five round fight.
