Andy Murray is to undergo back surgery to rectify a long-term problem and is likely to miss the rest of the season as a result.
The Wimbledon champion's lower disc problem forced him to withdraw from the French Open in May and has been an issue for almost two years.
He will undergo surgery next week and with only seven weeks remaining of the 2013 season he will almost certainly miss out on all remaining tournaments including November's World Tour Finals in London.
The Scot played a major role in Great Britain's Davis Cup victory over Croatia last week which saw them qualify for the World Group for the first time since 2008.
However Murray did look to be struggling at times and confirmed on Twitter of his decision to have surgery.
"Having operation on monday.. Will let everyone know how it goes.. Ill be "back" stronger," he tweeted on Thursday.
The world number three became Britain's first male Wimbledon singles champion since 1936 this year and will hope to have plenty of time to recover to contest in next year's first Grand Slam, the Australian Open in January.
A statement from his management company, 77, said: “Next week, Andy is set to undergo minor back surgery in an effort to clear up a long-standing back problem.
“The issue flared up again during the Rome Masters this year when Andy was forced to retire and he sought advice from a range of specialists in May.
“After a successful return on the more forgiving grass courts, Andy enjoyed success at Queen’s and Wimbledon, but after recently playing on hard-courts and clay, Andy once again sought medical advice about solving the issue once and for all. The aim is to be fully fit for the new season.”
