LAHORE - Pakistan, Sri Lanka and the West Indies are likely to participate in a four-day Twenty20 tournament, also involving hosts Canada that gets underway at Toronto next month. The tournament was to be held in July and the Bangladesh was the fourth team which has been replaced by Sri Lanka now. The sponsorship issues postponed the tournament and now it is expected to be played in October. "Pakistan will be participating in the quadrangular T20 competition involving Sri Lanka, West Indies and hosts Canada from October 10-13," a top board official said. The final decision came after a meeting of the members. Pakistan team already looking to fill the Champions Trophy void would be happy to take part in the event but their activity in September is yet to be finalised. The four-nation tournament was earlier scheduled for August 14 to 17, but later on it was deferred due to sponsorship problems.
