PV Sindhu and Lakshya Sen have pulled out of the Thailand Open Super 500 as the draws for the BWF World Tour event have been announced on Wednesday.
The Thailand Open marks the resumption of the World Tour after a gap of a month, marked by the Thomas and Uber Cup. 
World no. 3 men's doubles pairing of Satwiksairaj Rankireddy and Chirag Shetty will look for redemption of their form after a rather dismal show at the Thomas Cup, where they lost two matches against Indonesia's Bagas Maulana-Muhammad Shohibul Fikri and China's Liang Wei Keng-Wang Chang.
Satwik and Chirag - the top-seeded pairing at the event- will open their campaign against world no. 71 Nur Mohd Azriyn Ayub and Azriyn and Ta Wee Kiong of Malaysia
