Saina Nehwal won bronze in badminton women's singles at the 2012 London Olympics on Saturday after her Chinese opponent Wang Xin retired from the game following a knee injury.

It was India's third medal at the ongoing Olympics after Gagan Narang opened the country's medal account by winning a Bronze in men's 10m air rifle on Monday and Vijay Kumar got Silver in men's 25 metre rapid fire pistol on Monday.

World No. 2 Wang won the first game against Saina 21-18 and was leading the second game 1-0 before withdrawing from the game. She received medical treatment towards the end of the first game after straining her knee. She went on to finish off the game but had to retire in the second game.

The 22-year-old Indian shuttler created history on Thursday by becoming the first Indian woman to enter women's badminton singles semifinals in Olympics. However, she lost 13-21, 13-21 to world No.1 Wang Yihan of China in the semifinals on Friday evening.

In another event, Laishram Devendro Singh from Manipur stormed into the quarterfinals by beating 2008 Beijing Olympics Silver medalist Serdamba Purevdorj of Mongolia in the men's light flyweight (49kg) category.

The 20-year-old Indian outclassed the 2009 world champion 16-11. He displayed great footwork and quick hands, bringing his opponent down to the canvas twice during the fight.
