When a prized fighter has to pull out of a highly anticipated fight, there will be a deluge of reactions and opinions from all around, and that was the case with UFC featherweight champion Jose Aldo, had to withdraw from his scheduled UFC 189 fight with Conor McGregor, the fifth time he has had to pull out of a title fight due to injury.

Adding to the controversy was the mixed reports regarding the severity of the injury. Brazilian doctors diagnosed Aldo with a fractured rib, while the UFC previously released a statement, prior to Aldo's withdrawal, that the champion had a bruised rib.

UFC doctor Jeff Davidson was recently interviewed by Yahoo Sports about the matter, and said that the exact nature of the injury really doesn't matter in this case.

"Every individual has a different threshold for pain tolerance," Davidson was quoted in a report by Kevin Iole of Yahoo Sports" "Anyone who has an injury to the chest wall, they're never quite sure whether they bruised their rib, whether they broke or whether they tore the cartilage. All they know is that it hurts. It doesn't matter what the injury is, it hurts."

"Jose had pain, he felt uncomfortable and the bottom line is, he didn't feel like he could perform like he needed," Davidson added.

After suffering the injury during training, Aldo underwent a series of treatments to allow him to fight, which included plasma rich protein therapy (PRP), which did not work well enough to allow him to fight.

"The UFC never offered us additional money for Aldo to fight, and they did not pressure us," Aldo's trainer Andre Pederneiras said in a released statement. They let us know that if Aldo could not fight, McGregor would continue on the card against Chad [Mendes]. And they let us know that because it was the fifth time Aldo withdrew due to injury, they would make it for the interim title. There was no pressure and no offer of any money by the UFC for Aldo to fight. The only disagreement we had was in the diagnosis of the injury, between the doctors we consulted in Brazil, and the American doctors. Actually, Dana demonstrated genuine concern for Aldo's health."
