Did You Know?
A middleweight bout between Ronaldo Souza and Yoel Romero was originally booked for UFC 184 and later UFC on Fox: Machida vs. Rockhold. However, the bout was canceled both times due to Souza being struck with pneumonia and Romero pulling out due to a ligament and meniscus tear in his knee, respectively. The fight was later rescheduled for this event. See more
