Sri Lanka's proposed series of One-Day Internationals against Pakistan next month is in jeopardy due to a clash of dates with the cash-rich Indian Premier League. Sri Lanka had offered to play in the short series following a pull-out by Australia from a full tour of Pakistan in March-April due to security concerns. But the dates of the series – from April 23 to May 5 – are in direct clash with the inaugural Twenty20 league, to be played over 44 days at various venues in India from April 18 to June 1. Captain Mahela Jayawardene, key batsman Kumar Sangakkara and spin wizard Muttiah Muralitharan are among a host of Sri Lankan players contracted to play in the IPL. The Pakistan Cricket Board has said that it was willing to offer SLC $800,000 for the series of five ODIs, slated to be held from April 23 to May 5, but only if it sends its full team. A top BCCI official reported expressed his displeasure over the Pakistan tour to his counterpart in Sri Lanka over telephone. __
