A heavyweight bout between the 2001 K-1 World Grand Prix winner and former interim title contender Mark Hunt against Marcin Tybura was expected to serve as the event’s headliner. However on October 10, Hunt was removed from the bout due to “medical concerns”. He had recently admitted in an article trouble sleeping and said he’s begin to stutter and slur his words. The UFC released a statement claiming that “the health-related statements made by Hunt represented the first time UFC was made aware of these claims”. They also announced that it would be required that Hunt undergo further testing and evaluations prior to competing in any future bout. As a result, former UFC Heavyweight Champion Fabrício Werdum was chosen as his replacement.
