The Duke of Edinburgh will miss the Queen's trip to the East Midlands on Wednesday.
He was due to join the Queen and the Duke and Duchess of Cambridge in Nottingham before heading to Burghley House, near Stamford in Lincolnshire.
He's also pulled out of a garden party at Sandringham tomorrow as he continues to recover from a bladder infection.
Prince Philip, who was 91 on Sunday, only left hospital on Saturday.
The Duke became ill after the Diamond Jubilee River Pageant. He was standing in wet and cold conditions for several hours.
