Antonio Silva underwent surgery on Tuesday morning in Brazil, and the procedure was a success.

The Brazilian heavyweight, who suffers from acromegaly, underwent surgery to remove a pituitary gland tumor that has reemerged, and should get released from the hospital in Sao Paulo next Monday.

"The surgery was a success," Silva’s manager Alex Davis told MMAFighting.com. "It’s a head surgery, so it’s always complicated. They had to access the gland under the brain through the nose, so it’s not a simple surgery – especially for a fighter, who gets punched in the face for a living."

According to Davis, "Bigfoot" is anxious to get back in action again after suffering a first-round knockout against Andrei Arlovski at UFC Fight Night 51, but he will only fight again next year.

"He should get cleared to train again in two months," Davis said. "I think he will be ready to fight in five or six months. He wants to fight again. He’s disappointed with his last fight."
