Back surgery to end Murray’s season
LONDON – Wimbledon champion Andy Murray will have surgery on a long-standing back problem and miss the rest of the season.
“The aim is to be fully fit for the new season,” said a statement released by Murray’s management company on Thursday.
The third-ranked Murray will miss the season-ending ATP World Tour Finals in London on Nov. 4-11, along with the Masters events in Shanghai and Paris in October. There are 13 tournaments left on this year’s schedule.
Murray has had problems with his back before this year, but the injury flared up at the Rome Masters in May, forcing him to pull out of the French Open that month.
