These seniors had decided not to tour Pakistan for the Twenty20 tournament earlier due to security concerns.
It was a youth team which toured Pakistan at that time and they were accorded security arrangements generally accorded to a president.
Since the attack on the Sri Lankan team in Lahore in 2009 no foreign teams visited Pakistan for any test series. However after a decade Pakistan has been granted the opportunity to host a test series.
Captain Dimuth Karunaratne, Angelo Mathews and several other senior players are scheduled to join this tour, according to reports.
