White: Aldo withdrawal disappointing

Aldo suffered a rib injury during sparring last week, and while initial medical reports suggested the injury was merely a bruise, Brazilian doctors diagnosed a fracture which ultimately led to Aldo’s withdrawal.

As a result, McGregor will take on Chad Mendes for the interim bout at UFC 189.

Whilst Mendes is a rightful title challenger himself, Aldo-McGregor was the most promoted fight in the history of UFC and White was clearly frustrated by Aldo’s decision to withdraw.

"Jose Aldo has pulled out of five title fights," Dana said. Conor is ready to go, the No. 1 guy in the world, Mendes, is ready to go so it makes sense that they fight for the interim title," White said.

"Whenever Jose Aldo is ready we can make the fight to unify [the belts]. It was his decision [to pull out of the fight]. We don't feel great about it — we spent a lot of money promoting that fight, a lot of people were anticipating that fight. It's definitely disappointing."
