Andrew Flintoff is set to announce his retirement from all forms of cricket. The 32-year-old all rounder has aborted plans to fight back from a series of knee injuries. Flintoff, who has won the Ashes twice, last played in the fifth Test against Australia at the Oval in August of last year. He was due to return to action with Lancashire this summer, but that was shelved. And he had also lined up a deal to play Twenty20 cricket for Queensland in Australia this winter.
