Seemingly restored to full health, Bradman blazed two centuries in the last two games of the tour. However, when he returned to London to prepare for the trip home, he experienced severe abdominal pain. It took a doctor more than 24 hours to diagnose acute appendicitis and a surgeon operated immediately. Bradman lost a lot of blood during the four-hour procedure and peritonitis set in. Penicillin and sulphonamides were still experimental treatments at this time; peritonitis was usually a fatal condition. On 25 September, the hospital issued a statement that Bradman was struggling for his life and that blood donors were needed urgently.
