India lost three wickets in the second session to slump to 174-7 at lunch on day three of the second test against South Africa in Guwahati on Monday, with the hosts trailing by 315 runs and in danger of being asked to follow-on.

Washington Sundar (33) and Kuldeep Yadav (14) forged a 52-run partnership for the unbroken eighth wicket but India are still well short of South Africa's first innings total of 489.
