Andy Murray tweeted a picture of himself in hospital this morning with his thumbs up after minor surgery on his back.

The Wimbledon champion and world number three told followers the first thing he said when he came round from the operation was:"Did I win?"

Murray, 26, is unlikely to play again this season and will miss the ATP World Tour Finals at the O2 in November.

He underwent surgery in an attempt to fix a disc problem in his lower back. The injury forced him to withdraw from the French Open earlier in the season.
