Murray - I'm not backing out

Andy Murray vowed to continue his French Open campaign despite the back problems that almost forced him to quit during his dramatic victory over Jarkko Nieminen.

The world number four has been struggling with a niggling back issue all year but it was a back spasm, which he felt when he woke up on Thursday morning, that caused the trouble. Murray looked certain to be heading home for a set and a half, barely able to move or serve, but he carried on and turned things around to triumph 1-6 6-4 6-1 6-2.

The Scot is due to play Santiago Giraldo in Saturday's third round, and he is adamant he will be on the court. He said: "I'm going to try and carry on regardless, whether it's a bit sorer tomorrow or in two days' time, I'm going to carry on. I'll just try and do all the right things to recover as best as possible."

He added: "I'm not doing myself any actual damage by playing with what I have. I have had all the best advice from some of the top surgeons and physios. I'm confident that I'm doing the right thing."

Murray has so far declined to reveal what the original back problem is, but to hear him mention surgeons is a concern, even if he insists he is not risking his health by playing on.

The 25-year-old's main feeling afterwards was shock that he had managed to come through and that Nieminen had allowed him a way back.

"I didn't find it that satisfying," he said. "I just couldn't believe I had won. I guess when you're in that position, especially in a grand slam, emotionally it's pretty challenging, because you're only one or two points away from having to stop.

"I couldn't believe I was in a position to win at the end of the fourth set, so I was starting to get a bit edgy. Rather than it being satisfying, it was just quite emotional."
