Rohit Sharma, the captain of India's Test team, tested positive for COVID-19, which may make him questionable for the lone Test against England at Edgbaston.
If Rohit is unable to captain India during the England Test, it is unknown who would take his place.
The selectors named KL Rahul vice captain when the team was revealed in May, but he is not in England since he just suffered a groyne injury before to the home T20I series against South Africa.
The news of Rohit's positive test came through after the third day's play of the warm-up match against Leicestershire.
