Anderson Silva has reportedly checked out of a Las Vegas hospital after his freak leg break against Chris Weidman during mixed martial arts event, UFC 168.

Silva underwent emergency surgery immediately after breaking his left leg and will spend a few more days in his Las Vegas hotel before flying home to Brazil.

Silva's manager Jorge Guimaraes said that the ex-UFC middleweight champion was "fine...just sad and in pain."

The Brazilian cagefighter sent out a message to his fans on Instagram thanking them for their support.

"I want to thank all my fans and friends for their support and caring messages, I'm fine now and I need to be with my family, a good rest with my children and wife will help me in recovery. Thanks Brazil."

He also tweeted to his 4.5 million followers on Twitter, saying: "Brasil, I'm sorry, I didn't want to let you down I gave my best, I swear."

After the UFC 168 title rematch with Chris Weidman, the UFC released a statement regarding Silva's injury and the subsequent surgery.

"The successful surgery...inserted an intramedullary rod into Anderson's left tibia," the statement read.

"The broken fibula was stabilised and does not require a separate surgery. Anderson will remain in the hospital for a short while, but no additional surgery is scheduled at this time. Recovery time for such injuries may vary between three and six months."

At the age of 38, this gruesome injury casts serious doubts on Silva's fighting career.
