London: England all-rounder Andrew Flintoff is unlikely to be fit for next month's World Twenty20 due to the slow response of his right knee to an operation performed last month.
Flintoff, 31, had keyhole surgery on April 28 after damaging his knee playing for Chennai Super Kings in the Indian Premier League.
At the time, the England and Wales Cricket Board issued a bullish statement saying they expected him to return for the World Twenty20, which begins on June 5.
Yet Flintoff, in an interview with Sky Sports due to be shown on Saturday, has cast doubt on that prognosis.
"I'm making progress, and I've been on the bike for 45 minutes. But I'm still a while away from running – maybe a week and a half or so. One of the things we've got to be careful about is swelling, which is why we're constantly icing and monitoring it after one session before I can do the next one," he told Sky News.
England's opening game in the World Twenty20 is against Holland at Lord''s in 19 days'' time, but Flintoff''s presence there always looked far from optimistic despite his selection in the 15-man squad.
