Andy Murray’s wrist injury has ruled the World No.3 out of next week’s Japan Open in Tokyo.

Although scans have shown there is no long-term damage, the Scot did not want to risk his participation in the end-of year ATP World Tour Finals at London’s 02 Arena.

This damage was aggravated in Britain’s recent Davis Cup defeat is on his left wrist, while Murray has previously been out of action for three months with an injury to his right wrist.

A statement on the 22-year-old’s website read: “Unfortunately, Andy has to withdraw from the ATP Tokyo Tournament.

“Andy is disappointed not to be competing in Japan, but on the basis of medical advice, he has decided to give his left wrist further time to recover.

“His injury is improving on a daily basis and Andy is very close to resuming full-training. The wrist will be assessed again this weekend.”
