India reached 91 for three against South Africa at lunch on the first day of the opening Test of the two-match series here on Tuesday.

Invited to bat, India were in a spot of bother at 24 for three before Virat Kohli (33 not out) and Shreyas Iyer (31 not out) rode on luck to stabilise the visitors' innings with unbeaten 67 runs for the fourth wicket.
