"Karunuday Singh has been given the wild card upon the request of the sponsors," Tournament Director Manpreet Kandhari said in a release.
Vishnu Vardhan had earned the wild card by winning the national hard court championship in October 2014.
"In the event of Saketh Myneni moving into the main draw on his own, his wild card will be awarded to Ramkumar Ramanathan," the release added.
India's number one singles player Somdev Devvarman is the defending champion at the event.
