India's white-ball captain Rohit Sharma and all-rounder Ravindra Jadeja have started their rehabilitation at the National Cricket Academy in Bengaluru after being ruled out of the upcoming Test series in South Africa due to injuries.

The two senior players were seen at the NCA with India Under-19 captain Yash Dhull in his social media posts.

The India U-19 team is currently camping at the NCA ahead of the Asia Cup, beginning in the UAE from December 23.

Rohit, who was named ODI captain last week replacing Virat Kohli, was named as vice-captain of the Test team for the South Africa Test series starting on December 26 before a hamstring injury during training ruled him out.

His expected recovery time is between three to four weeks.

India 'A' captain Priyank Panchal was named in place of Rohit in the Test squad, which reached South Africa on Thursday for the series.

The senior opener, who took charge as T20I captain against New Zealand last month, is expected to be available to lead the team for the ODI leg of the South Africa tour, which is to take place in January.

Jadeja has been ruled out of the South Africa tour due to a knee injury which he sustained during the home New Zealand Test series last month.

He may take a longer time to recover from his injury.
