Murray out of Turkey relegation clash

Murray, who also missed the tie against Lithuania in March, said he would continue to make decisions on a match-to-match basis and insisted that it was time Great Britain got used to winning without him.

"I've given a lot of reasons for not playing and I do think that it's time for us to start winning ties, having young players get used to winning," the 23-year-old said.

"The number one player from Turkey (Marsel Ilhan) is ranked 120 in the world and he's a tough player. Right now its important that the guys get used to winning and beating teams like Turkey and I think they will do."

The International Tennis Federation rules mean that Murray will have to play at least one Davis Cup tie in the next two years to be allowed to take part in the London Olympics.

But Murray insisted he is not retiring from Davis Cup tennis, merely making decisions based on what is best for his career at the time.

"I'm not by any means retiring from Davis Cup," he said.

With British number two Alex Bogdanovic also having ruled himself out of the July 9-11 tie, new captain Leon Smith will likely call on world number 259 Jamie Baker and James Ward, world number 342, for the singles. Ken Skupski and Colin Fleming are currently Great Britain's doubles team of choice.

"Obviously I am disappointed that (Murray) is not going to be part of the team, because he is one of the best players in the world," Smith said.

"But I accept his decision and I believe that we still have the players available to win this tie and to make the most of the opportunity."

Ilhan is Turkey's only recognisable player, with Ergun Zorlu and Tuna Altuna the country's only other players ranked inside the top 1000, at 859 and 924 respectively.
