Pietersen, Harmison and Anderson could all be hunting IPL deals
England players will be free to play in part of the next Indian Premier League season if India release 20 players for the inaugural English version in 2010.
The England and Wales Cricket Board had said centrally contracted players could not play IPL cricket in 2009.
But IPL boss Lalit Modi told BBC sports editor Mihir Bose: "I am informed by ECB chairman Giles Clarke they would be available for the month of April.
"But not for the month of May because they have international commitments."
England finish their tour to the West Indies on 3 April and have no further cricket until 7 May, the scheduled date for the first Test against Sri Lanka at Lord's.
However, that tour is in serious doubt because Sri Lanka's leading players have been allowed to honour existing IPL deals.
The first IPL season was staged between 18 April and 1 June 2008 and the England players were the only international stars missing.
Ideally they would like the (England) players there for the duration but a franchise would not like to have a player for less than a month

"The chairman of the ECB and I have had extensive dialogue," said Modi.
"We will both look at trying to develop a clear window that does not clash with each other.
"The position of the ECB is it has no problem giving a no objection certificate to English players to participate in the next edition of the IPL.
England players can play in IPL - Modi
"But it comes with a few strings attached, which we in the IPL and BCCI (Board of Control for Cricket in India) need to review and see if we can live with those strings or not.
"One of the conditions attached is that the IPL and the BBCI needs to release 20 contracted Indian players for the English Premier League.
"The franchises will need the players for a month because they need to build a team. Ideally they would like the players there for the duration but a franchise would not like to have a player for less than a month."
Modi said the IPL and BCCI would review conditions stipulated by the ECB at the next IPL governing council meeting in November.
