UFC featherweight champion Jose Aldo "is in deep pain," but he still wants to fight Conor McGregor at UFC 189.

News broke on Wednesday that the Nova Uniao star broke his rib during a sparring session in Rio de Janeiro for his July 11 bout with Conor McGregor in Las Vegas. Despite the injury, "Scarface" still plans on fighting "The Notorious."

"He cried. He wants this fight bad, everybody invested a lot in this," Nova Uniao head coach Andre Pederneiras told Combate. "I was with him the whole afternoon. He’s heartbroken. He wants to fight anyway. Now we have to wait for the exam results. Aldo is in deep pain."

Sources close to the situation told MMA Fighting that Aldo fractured his rib while training with 5-0 lightweight Alcides Nunes, and Pederneiras won’t make the decision to take Aldo from the card before talking with his doctors on Wednesday.

"If the fracture is really confirmed, Aldo will have to stop training, do nothing for three or four weeks until it’s fixed, and then he would be able to do any exercise without forcing his rib," the coach said. "And then he would need a normal time to do a training camp: three months. I believe this fight wouldn’t happen before October."

UFC 189 takes place at the MGM Grand Garden Arena in Las Vegas. The fight card features another title fight in the co-main event, with welterweight champion Robbie Lawler defending his title against Rory MacDonald.
