Yuvraj Singh, who recently underwent cancer treatment, has been included in the probables.
However, it is not certain whether the southpaw will make the cut for the final 15 that will be announced in August. Off spinner Harbhajan Singh, who has been out of the Indian team for quite some time, has also been included in the preliminary squad.
Paceman Laxmipathy Balaji, who has not played any T20 for his country, along with some other promising youngsters was also part of the provisional list.
