The Pakistan Cricket Board might not be able bring about major changes in the national team in the wake of the side's dismal performance in the T20 World Cup as that could lead to a confrontation with senior players, according to sources. PCB's governing board, scheduled to meet here on Saturday, will take cognizance of white-ball head coach Gary Kirsten and senior team manager Wahab Riaz's reports submitted to chairman Mohsin Naqvi.
