As is the story with most UFC pay-per-view cards, something has to go wrong. And UFC 221 is no exception.
In addition to this main card losing its main event a few weeks back after interim (or undisputed?) middleweight champion Robert Whittaker was forced to withdraw, the man who replaced him (Yoel Romero) missed weight Friday, tipping the scales at 187.7 pounds after two attempts to reach the 185-pound limit.
Romero is no longer eligible to win the interim title, but his opponent (Luke Rockhold) is.
It's not the most star-studded of cards, but UFC 221 has a lot of fun fights throughout, including the co-main event featuring heavyweights Mark Hunt and Curtis Blaydes.
