India are placed fourth in the latest International Cricket Council (ICC) Test rankings, released on Thursday with 111 points - 19 points less than Australia.
India will not play a Test match until their series in South Africa in November.
Sri Lanka, at fifth position, have 99 rating points compared to South Africa's 98.
The Proteas lost the first Test to Sri Lanka by an innings and 153 runs at the Sinhalese Sports Club (SSC) in Colombo.
South Africa will make an all-out effort to win the second and final Test and level the series but they cannot overtake the islanders in the rankings.
"Defeat at the SSC means a drawn series is now the best it can hope for, but it cannot overtake Sri Lanka and claim fifth place in the ICC Test Championship table," an ICC statement said.
Shaun Pollock, 13th in the Test bowling rankings, is set to return for the second Test, and may replace fellow seam bowler Andre Nel, who dropped three places to 17th after taking one for 114 in the first Test.
If England win the series against Pakistan, they will recapture the second place in the table, a spot currently occupied by Pakistan. Australia are 10 points clear at the top of the rankings.
England registered an innings win over Pakistan at Old Trafford, Manchester in the second Test. The third match starts at Headingley on Friday.
The table reflects the annual update August 1. The update is carried out to ensure it continues to reflect recent form with older results being discarded.
