Novak Djokovic says he is not sure if he will play in next month's Australian Open because of an elbow injury.
Djokovic, currently ranked 12th in the ATP rankings, was scheduled to play in the Mubadala World Tennis Championship in Abu Dhabi, but the injury caused him to withdraw.
"I am terribly disappointed that I am forced to withdraw from the Mubadala World Tennis Championship," Djokovic said. "Unfortunately, in the past few days I started to feel pain in the elbow and after several tests, my medical team has advised me not to risk anything, to withdraw from the tournament and to immediately continue with the therapies
Djokovic retired from his Wimbledon quarterfinal match against Tomas Berdych because of the right elbow issue.
