Rafael Nadal has withdrawn from next week's Sydney International due to a foot injury.
Tournament officials revealed that Nadal's left foot, which he injured three months ago, has still not healed sufficiently for the Spaniard to take part in the event.
The world number two had already pulled out of this week's ATP event in Chennai, India and must now be considered doubtful for the Australian Open, the season's first grand slam, which begins on January 16.
Nadal told Sydney tournament officials: "I am very sorry that I cannot play in Sydney because I was looking forward to coming there for the first time."
Sydney tournament director Craig Watson said: "For Rafael, his health and fitness is the priority and we wish him the best for a speedy recovery."
