London - England all-rounder Andrew Flintoff has returned to England from South Africa, where he was playing in the Indian Premier League, to undergo surgery on his right knee, the England and Wales Cricket Board confirmed on Friday.
The surgery means Flintoff is likely to miss some or all of the upcoming two-Test series against the West Indies and may also make him doubtful for the World Twenty20 in June and the Ashes series starting in July.
