Hip problems mount for Murray
Andy Murray has withdrawn from the Brisbane International amid concerns that his long-standing hip problem is not showing the necessary signs of improvement.
The 30-year-old is now a major doubt for the Australian Open, having admitted that a lengthy period of rehabilitation has not brought about the recovery he had hoped for in his right hip.
Unfortunately this hasn't worked yet to get me to the level I would like, so I have to reassess my options.Andy Murray
More ominously, Murray also stated that surgery on the injury may not be the answer to his issues, placing his long-term future in the game in question.
The three-time Grand Slam champion posted on Instagram: "I've obviously been going through a really difficult period with my hip for a long time and have sought council from a number of specialists.
"Having been recommended to treat my hip conservatively since the US Open, I have done everything asked of me from a rehab perspective and worked extremely hard to try get back on the court competing.
"Having played practice sets here in Brisbane with some top players, unfortunately this hasn't worked yet to get me to the level I would like, so I have to reassess my options.
"Obviously continuing rehab is one option. Surgery is also an option, but the chances of a successful outcome are not as I high as I would like, which has made this my secondary option and my hope has been to avoid that."
Former world number one Murray has been out of action since losing to Sam Querrey in the quarter-finals of Wimbledon in July of last year.
With Murray seemingly unlikely to feature in Melbourne, Roger Federer is 2.75 to retain his Australian Open title, with Alexander Zverev priced at 10.00 and Grigor Dimitrov available at 10.00.
