Injury-plagued Andrew Flintoff has been ruled out of competitive cricket for the entire summer, his county Lancashire have confirmed.
The all-rounder, who has undergone two knee operations in the last year, was set to return to action this week, however the Red Rose medical staff have decided he is "not quite ready" to compete.
Flintoff, 32, had been due to play in a one-day match against Yorkshire second XI on Monday, only for Lancashire to decide that a limited-overs clash could be too "vigorous" for him.
The possibility of Flintoff playing in Tuesday's three-day game was then held open but upon further consideration his comeback has been delayed once more.
"Following consultation with Andrew Flintoff, Andy Williams (Flintoff's surgeon) and our own medical team, Lancashire County Cricket Club have today confirmed Flintoff will not be returning to competitive cricket for the remainder of the 2010 season," said a statement by Lancashire.
Flintoff, who retired from Test cricket during the victorious 2009 Ashes series, has not played since major knee surgery last August, undergoing a further operation in January.
The delay also means that he will not be able to compete for the Chennai Super Kings in September's Airtel Champions League Twenty20.
The Indian Premier League franchise gave Flintoff the opportunity to prove his fitness in time by naming him in their preliminary squad for the tournament.
The double Ashes winner also looks unlikely to return in time for England's one-day series against Australia this winter.
"Whilst Andrew has made significant progress, the combined opinion is that he is not quite ready for a return to cricket," said Lancashire's cricket director Mike Watkinson.
"He will continue his rehabilitation into the winter months and we will constantly monitor and review his progress so that he is better equipped for a return to action."
