According to our friends over at MMANews.com, Mauricio "Shogun" Rua has undergone successful knee surgery. The surgery was performed by Dr. Mario Namba.

"The surgery was a success, I'm following Mauricio for the last few months and this problem was identified before his last fight, as a professional he decided to keep his agreement to fight and I respect that, he's young and very strong, I'm sure that his recovery will be fast and he will be ready to fight again very soon".

Shogun for his part seemed positive and ready to go back to work for the belt.

"I know about my mistakes in the fight against Forrest," said Shogun. "I will never use this surgery as an excuse for my loss, I have all the responsibility for the bad result. Now I just want to look for the future. I would like to thank all my fans that are supporting me in this difficult moment and I promise you all that I will be back better than ever. I know that I lost the first battle but not the "war" for the UFC belt."
