Andrew Flintoff announced his retirement from all cricket on Thursday as he admitted defeat in his battle against a persistent right knee injury. It is with both disappointment and sadness that I am today (Thursday) announcing my retirement from all forms of cricket, former England captain Flintoff said in a statement released by his agents, International Sports Management (ISM). The decision to end my career came yesterday (Wednesday) after consultation with medical advisers, added the 32-year-old all-rounder, who quit the Test format after helping England regain the Ashes last year. Having been told that my body would no longer stand up to the rigours of cricket, I had no alternative but to retire. I would like to thank my family, Lancashire Cricket Club, England, all my sponsors, friends and advisers for all the help and support they have given me throughout my career.
