Murray calm over back issue

Andy Murray has insisted he is not harming his fitness ahead of Wimbledon and the Olympics by playing in the French Open.

The British number one has endured plenty of injuries throughout his career with the latest being a back problem that began at the end of last year.
Murray suffered a back spasm on Thursday morning ahead of his second-round match at Roland Garros against Jarkko Nieminen, which almost forced him to quit, but he battled through it to emerge a 1-6 6-4 6-1 6-2 victor.
With the summer being particularly busy this year because of the Olympics it had been suggested that he avoid the French Open to make sure he is as fit as possible, but Murray is confident he is not doing himself any serious harm.
"It's a completely different thing to what I had beforehand. So if it was the same thing, then, yes, I would be really, really concerned about Wimbledon and obviously the Olympics," Murray said.
"But so long as what I'm getting told by doctors and the physios is, if it is just a muscle spasm, then that's nothing to be overly concerned by, (then I will play).
"But when they happen they are very difficult to shake off, especially when it's early morning. It takes a bit of time for your body to warm up and stuff. So I'm not doing any permanent damage by finishing a match like I did."
