The two Islamabad United players will be replacing Babar Azam and Ruman Raees for the tournament.
The decision has been taken by the management due to their solid performances in the inaugural edition of the inaugural edition of the Pakistan Super League (PSL).
Sharjeel Khan scored the first ever century in the PSL against Peshawar Zalmi on Sunday evening. He has scored 287 runs in the cricketing league.
Sami, on the other hand, has grabbed eleven wickets in the tournament so far with best figures of 5/8.
