Chennai: Team India ace batsman Sachin Tendulkar faces a race against time to be fit for the second Test against South Africa after aggravating a groin injury, captain Anil Kumble said on Sunday.
The star batsman, who needs 172 runs to take over from West Indian Brian Lara as Test cricket's leading run-scorer, did not field for most of the final day's play in the first Test which ended in a draw here.
"Sachin aggravated a groin injury he picked up in Australia and also has an upset stomach, but hopefully he will be fit for the second Test," Kumble told reporters.
The second Test starts in Ahmedabad on Thursday.
Former Indian physiotherapist John Gloster had recommended a three-week rest for Tendulkar after the Australian tour ended on March 4.
The 34-year-old, however, declared himself fit for the South African series.
Tendulkar, who fell for zero in India's only innings here, has 11,782 runs from 147 Tests, second behind Lara's record tally of 11,953 runs.
The prolific Indian is already the top one-day batsman with 16,361 runs and holds the world record of 39 Test and 42 one-day centuries.
