Novak Djokovic says he had a "small medical intervention" on his bothersome right elbow.
The 12-time grand slam champion and former No. 1-ranked player wrote on Instagram on Friday: "It seems like I am on the good road now to full recovery."
Djokovic sat out the last half of 2017 because of problems with his racket-swinging right arm, saying it had been bothering him for more than a year.
The 30-year-old Serb made a late decision to enter the Australian Open last month.
He was clearly hampered by the elbow in a straight-set loss to Hyeon Chung of South Korea in the fourth round.
