Tennis news: Andy Murray pulls out of Brisbane International as hip problems continue

Andy Murray has pulled out of the Brisbane International due to a hip injury, making him a major doubt for this month's Australian Open.
The 30-year-old had been set to return to competitive action this week having been sidelined with hip problems since his Wimbledon quarter-final defeat in July.
Murray was beaten at an exhibition event in Abu Dhabi last week, but looked better as the set went on and he was set to make a first competitive appearance in Brisbane this week.
But a statement on the tournament's website on Tuesday morning said the British number one had pulled out "due to pain in his right hip".
It is the latest injury setback for Murray in the past 12 months. The Scot won only one title last season, in Dubai, and that was on the back of a month off after being diagnosed with shingles in February.
He then was forced to pull out of the Miami Open in March due to an elbow problem, while he was also unable to carry out several commitments after contracting flu, which ruled him out for six weeks and saw him Great Britain's Davis Cup quarter-final against France.
He then suffered from a heavy cold in the build-up to the French Open, which restricted his practice and required antibiotics, yet he still managed to reach the semi-finals where he lost to Stan Wawrinka.
In July, Murray was unable to practise four days before the start of his Wimbledon title defence after a long-standing hip problem flared up. The Scot declared himself fit and limped through his five matches, but suffered his joint earliest exit from SW19 in a decade, beaten 3-6 6-4 6-7 (4/7) 6-1 6-1 by American Sam Querrey in the quarter-finals.
The hip injury forced Murray to withdraw from the Rogers Cup in Montreal and the Western & Southern Open in Cincinnati in Augest. In his absence, Rafael Nadal replaced him as world number one. The British number one then pulled out of US Open two days before the start of the tournament, saying he was not fit enough to do himself justice.
In September, Murray announced that he was unlikely to play again in 2017 in order to undergo an "extended period of rest and rehabilitation" - ruling himself out of the ATP Tour events in Beijing and Shanghai, plus his defence of the ATP Finals in London.
The Australian Open starts in less than two weeks.
