Egypt's world champion Ramy Ashour has pulled out of next week's British Open due to an Achilles injury.
The 28-year-old was due to compete after returning to action following a four-month absence with a knee problem.
However, it has been confirmed that Ashour, who won the British title back in 2013, has picked up a fresh injury blow.
England's Nick Matthew is seeded third for the tournament, while Egypt's Mohamed Elshorbagy and Gregory Gaultier of France are seeded first and second respectively.
