Just two days before UFC made its debut in Australia, Ben Rothwell has fallen ill and will not be able to fight Cro Cop on Feb 20th. Rothwell's illness is currently disclosed. Anthony Perosh replaces ill Ben Rothwell. Perosh has not fought in the UFC since 2006 but he is currently 5-2 in the Cage Fighting Championship organization.
Elvin Sinosic sustained a shoulder injury during training forcing him to pull out of the fight. Instead of replacing the injured Sinosic UFC has decided to completely pull the fight.
