Dana White clarified the UFC’s new policy mandating all main events be five round fights. The policy goes into effect for all main events after UFC 133.

While this will not effect most of the scheduled UFC pay per view cards through UFC 137, with championship fights announced for those cards, it will likely start with “UFC on Versus 5” with a fight between Chris Lytle and Dan Hardy.

Many are left wondering how the policy will affect the problematic scenarios where fighters are scratched off cards due to injuries.

For example, in the case of UFC 131 where Shane Carwin replaced an ailing Brock Lesnar by fighting Junior Dos Santos. In that case, Carwin would have signed a new bout agreement that would have made the fight five rounds regardless of the short notice.

However, if a situation occured like UFC 130, where both Gray Maynard and Frankie Edgar dropped out and a light heavyweight bout between Matt Hamill and Quinton “Rampage” Jackson was moved to the main event, the fight between Hamill and Rampage would have remained a three round bout.
