The Indian team suffered a major blow as far as the women's team was concerned when Saina and doubles specialist Jwala Gutta pulled out of event.
Saina opted out of the competition, to be held from May 19 to 26, after she failed to recover fully from a hairline fracture on the small toe of her left foot.
The world number two had suffered the fracture before the India Open Super Series last month and aggravated the injury during the tournament, where she had crashed out in the second round.
National coach Pullela Gopichand said while Saina's absence would be a big blow but it would a great chance for the 17-year-old Sindhu to stand up and be counted.
