Anderson Silva has withdrawn from UFC 198 with only days left before the pay-per-view event in Curitiba, Brazil.
UFC officials confirmed to Yahoo Sports on Tuesday that the former middleweight champion was forced from his bout against Uriah Hall due to “abdominal pain that may require gall bladder surgery.”
UFC medical consultant Jeff Davidson told the site that Silva’s symptoms were consistent with “acute cholecystitis,” an inflammation of the gallbladder often caused by gallstones blocking the passage of fluids. It is the primary reason for patients having their gallbladders removed.
