Despite being released from the hospital, a recovering Aldo doesn’t know yet of his upcoming bout against Alexander Volkanovski at UFC 237 will still happen.
"I'm still not 100 percent. I couldn't possibly be," Aldo said to ESPN. "But I think I'll be good to go. I was going to the doctor today, but I decided to do it tomorrow. Then I'll talk to him and hope for the best."
Aldo, if cleared to compete, would be fighting for the first time since defeating Renato Moicano by second round TKO at UFC Fight Night Fortaleza.
The former featherweight champion says the infection was so bad that he couldn’t even walk anymore.
"It all happened [last] Monday. I was having some wrestling practice and my knee got a little burned. A little bacterium got inside my knee," Aldo said. "I got home and I had a fever. My knee on Wednesday was huge and swelling -- that's what took me to the hospital. The first session of antibiotics had no effect, but everything bad got out of my system by Saturday. I'm having one practice a week to come back strong. I couldn't even put my foot on the ground. I couldn't walk. I thought I'd have to pull out, I thought I wouldn't make it. But Dedé and the doctor got me a little calmer. I thought when the liquid that was on my knee got out of there, I'd be back quickly. Then I got through."
UFC 237 takes place on Saturday, May 11 from the Arena Da Baixada in Curitiba, Brazil with Rose Namajunas and Jessica Andrade headlining. Fightful is providing live coverage of the event, with a post-show podcast to follow.
