''Quite unacceptable behaviour against the background of Sri Lanka's signed agreement with the ECB,'' Morgan was quoted as saying by the Daily Telegraph.
The president has pointed out that only last month the ICC reaffirmed the primacy of Test cricket with the unanimous agreement of all full members.
''Everyone signed up to the order of priorities, starting with ICC events like the World Cup. In second place come events under the FTP,'' he said.
A five-member SLC delegation is travelling to India next week to finalise a 40 million dollar in which the island nation's board will release their players to play in the second leg of the IPL.
However, the said deal will lead to the cancellation of the two-Test series in England scheduled to be held in May next year.
The Sri Lanka series clashes with the latter stages of the IPL and players like captain Mahela Jayawardene, off-spinner Muttiah Muralitharan and wicket-keeper batsman Kumar Sangakkara have signed to play in the lucrative T20 tournament.
