Fourth seeds Sania Mirza and Elena Vesnina's doubles campaign at the Mercury Insurance Open came to an end following a right-hand injury to the Russian.

Up against Elena Bovina of Russia and Jie Zheng of China, the Indo-Russian pair was trailing 2-5 in the opening set when they decided to opt out of the contest.

Sania is already out of the singles event after losing the first round match 2-6, 3-6 to world No 36 and 15th seed Sara Errani of Italy.

She also had suffered defeat in the first round of the Citi Open.
