It is expected to be a 17-member squad that will travel to South Africa and the main call will be whether India would go with four frontline pacers and three specialist spinners or five specialist pacers with two slow bowlers.
Hardik Pandya, who was rested for the Test series against Sri Lanka, and Parthiv Patel were also added to the touring squad.
India Test squad vs South Africa: Virat Kohli, Murali Vijay, KL Rahul, Shikhar Dhawan, Cheteshwar Pujara, Ajinkya Rahane, Rohit Sharma, Wriddhiman Saha, Ravichandran Ashwin, Ravindra Jadeja, Parthiv Patel, Hardik Pandya, Bhuvneshwar Kumar, Mohammed Shami, Ishant Sharma, Umesh Yadav, Jasprit Bumrah.
Bumrah has been phenomenal in the limited overs format for India and was supposed to get his maiden call-up for the Sri Lankan Test series, but as luck would have it he will get a chance to wear the national whites on the Protean soil.
Virat Kohli will miss the three-match Twenty20 series against Sri Lanka starting on December 20, to help the captain prepare for the tour of South Africa. "Considering the his brilliant performance in last year's Ranji Trophy, he was an unanimous choice", Prasad said.
Talking about the youngsters who made way into the Indian side for the first time, "The players selected themselves".
Chinaman Yadav missing out on a Test nod was "unfortunate", according to Prasad.
India will play three Test matches, six ODIs and three T20I matches. "But he is a fine bowler and over a period of time, we would see him grow", the former Andhra stumper said.
The three Tests will be played between 5th and 28th January with Cape Town, Centurion and Johannesburg being the venues.
The squad for T20Is: Rohit Sharma (Capt), Rahul, Shreyas, Manish, Dinesh Karthik, MS Dhoni, Hardik, W Sundar, Yuzvendra, Kuldeep, Deepak Hooda, Bumrah, M Siraj, Basil Thampi, Jaydev Unadkat.
