After dealing with back problems all season, Andy Murray underwent minor surgery on Tuesday. The Wimbledon champion is skipping the Asian swing to recover and is considered doubtful to play the ATP World Finals in London.

After surgery, Murray joked: “First thing I said when I came round was 'Did I win?' #somethingsneverchange.”

Murray later tweeted his thanks to the hospital staff.

“After spending two days in hospital you realize and appreciate how amazing a job careers, nurses, doctors etc. do in hospitals all over the world looking after people who are in need," Murray wrote. "Thanks to everyone at hospital for looking after me and putting me back together again.”
