Karan Rastogi's two-day wait for the qualifying round at the Mumbai Open came to a disappointing end as he had to pull out of his first round against fellow-Indian Purav Raja on Monday.
Rastogi was 6-5, 5-7, 1-3 down when he suffered cramps and had to quit.
The other Indians still in contention for a berth in the ATP main draw are Navdeep Singh, Yuki Bhambri and Raja.
Raja will now play Japan's Toshihide Matsui in the final qualifying round.
Rastogi has received a wild card for the doubles event, where he will team with India's Mustafa Ghouse.
