Former Ultimate Fighting Championship middleweight champion Anderson Silva admitted in a press conference that he thought his career was over when he sustained a gruesome leg injury late last year.

Silva said in a press conference on Tuesday that he doesn't want to think about his previous fight against Chris Weidman, saying that it was the worst moment of his career.

The 39-year-old Brazilian, who broke his fibula and tibia during his rematch with Weidman in December last year, admitted that his career was over when he felt that his leg was broken.

"It's something I don't like to remember too much," Silva said via Yahoo Sports. "I went through the worst month of my life. It was a lot of pain the moment when I broke my leg. When I realized my leg was broken, I thought my career was over."

"A million things went through my mind."

Silva also added that he was very depressed during the first several weeks after the surgery as he thought things would never be the same again. While he is still struggling to regain his confidence, Silva said that he is very motivated to return strong to the Octagon.

"In the beginning it was a trauma for me, but not anymore," Silva said. "I think that I'm coming back in a new phase of my life. It wasn't a good experience, but I don't think it's going to be a hinder on me.

"My motivation to fight is always the will inside me to fight. I'm more mature. I'm very happy to be able to come back and do this again."

The former middleweight kingpin is set to make his return to action at UFC 183 on Jan. 31 against Nick Diaz. After his fight against Diaz, Silva said that he intends to finish the remaining fights in his UFC contract and possibly more.

"I intend to do all of my fights," Silva said. "And Dana said before the seven fights are over, so you don't run away, we'll renegotiate your contract again. He's the boss. It's all good."
