When Georges St-Pierre vacated the UFC middleweight title he won from Michael Bisping at UFC 217, it appeared that the convoluted middleweight title picture would finally have some clarity. Robert Whittaker, who won an interim title by earning a hard-fought split decision over Yoel Romero at UFC 213, was promoted to the undisputed champion and quickly booked to make his first title defense on Saturday at UFC 221 against Luke Rockhold. Unfortunately, Whittaker fell prey to injury and Rockhold, who was upset with the middleweight title situation all of last year, is now set to compete for his own interim title against Romero instead.
