Also aged 27, Thilini Jayasinghe was the oldest female athlete to compete for Sri Lanka at the London Summer Games. She had previously competed in the 2008 Summer Olympics. Jayasinghe qualified for the Games after the withdrawal of a South African badminton singles player led to a quota spot being re-allocated to Sri Lanka because of her world ranking of 109. She said before her event that she was "happy" to enter her second Olympic Games and would endeavour to reach the second round. Jayasinghe was placed in Group M of the women's singles badminton tournament on 29 July and was drawn against Ratchanok Intanon of Thailand. Inthanon made Jayasinghe vulnerable to attack and defeated the Sri Lankan player 21–13 in the first game. She continued strongly and beat Jayasinghe 21–5 in the second game to secure the victory. In her second group match against Portugal's Telma Santos, Jayasinghe was eliminated from contention from a 21-9 and 21–11 defeat.
