Warne expected to announce retirement

Shane Warne is set to announce his retirement from one-day cricket this afternoon.

Warne is expected to make the announcement when he arrives in Sydney as part of the Australian team for tomorrow's first final of the tri series against England at the SCG.

Warne will play in the cricket World Cup in southern Africa starting next month and then quit the one-day arena.

Warne is on the comeback trail after dislocating his shoulder last month but has said recently that would give up one-day cricket in order to further his Test career.

The 32-year-old has taken 288 wickets from 191 one-day internationals.
