Jasprit Bumrah is in danger of not travelling to Sri Lanka for India's two-Test series in August. Cricinfo has learned that the BCCI medical team has advised Bumrah not to rush back to action as he needs more time to completely recover from the left knee issue he has been nursing since the T20 World Cup earlier this year.

Bumrah has not bowled since the second ODI of the England series in Cardiff on July 16. He was ruled out of the final match of the series, played at Lord's, with BCCI saying an impact injury while fielding in the Cardiff ODI was the reason.

It is learned that immediately after the England series got over, Bumrah took an injection to the knee based on the plan drawn up by the BCCI medical team for his long-term fitness.

Bumrah reached the BCCI's Centre of Excellence (CoE) in Bengaluru this week and underwent fitness tests. It is understood that the medical team felt Bumrah could risk sitting out for an extended period if he returned to bowling right away as that could potentially aggravate the issue.

Details of the exact nature and extent of the injury are yet to be confirmed, but Bumrah had travelled to the CoE in late March as well to get conditioning and fitness clearances for the IPL, which had come a day prior to Mumbai Indians' season opener. Bumrah played 13 matches in the IPL season, sitting out MI's last fixture.

India are already without the services of Harshit Rana and Nitish Kumar Reddy, who are out with hamstring and quadriceps injuries, respectively. Washington Sundar has also been ruled out of the first Test with a hamstring injury, while Akash Deep is in the middle of a long layoff following stress reactions on his back.

The first Test begins on August 15 in Galle and the second on August 23 at the SSC in Colombo. Ahead of the series, the team will play a three-day practice match in Colombo, starting on August 7.

The series in Sri Lanka is India's first in the World Test Championship cycle since the 2-0 home defeat to South Africa in November. Before that, they had drawn a five-Test series in England 2-2 and beaten West Indies 2-0 at home. India are fifth in the WTC standings, while Sri Lanka are sixth.
