The injury forced Zii Jia, ranked world No 8, to withdraw from his final Group A match against China’s Li Shi Feng in the BWF World Tour Finals in Hangzhou, China, on Friday.

A statement from his team said the priority is to get Zii Jia back to full health and peak physical condition before he returns to the court.

Zii Jia, bronze medallist at the Paris Olympics, was leading 15-11 in the second game against Shi Feng when he had to retire after suffering the injury. He had taken the first game 22-20.

He was not allowed immediate treatment by the tournament officials before the second game was eventually stopped and he was taken off the court in a wheelchair.

According to the new BWF rules, players are not allowed medical treatment during the game and must wait until the break. The BWF rules also state that all results are nullified if a player concedes a walkover.

Zii Jia had won his two earlier Group A matches, defeating Taiwan’s Chou Tien Chen 21-13, 21-15 and Denmark’s world No 2 Anders Antonsen 21-14, 21-19.
