Middlesex will represent England in the Champions League
The second edition of the Champions League Twenty20 cricket tournament could clash with next year's rescheduled Champions Trophy.
The Twenty20 event will be held between 25 September and 11 October 2009, with the ICC-sanctioned Champions League set to be played at about the same time.
The 2008 Champions Trophy was postponed because of security fears in Pakistan.
Dates for the Champions Trophy could be finalised on Tuesday at an executive committee meeting of the ICC.
The inaugural Champions League was pushed back to December because it had originally clashed with the Trophy.
This year's tournament will feature the two top teams of the domestic competition in India, South Africa and Australia, and English Twenty20 Cup champions Middlesex and a team from Pakistan - all battling for £3m.
The 2009 edition will be expanded to 12 teams with a total of 23 matches.
The idea for the Champions League was developed by the cricket authorities of England, India, South Africa and Australia.
