Novak Djokovic is unsure if he'll play his fourth-round match at the Australian Open after saying he suffered a muscle tear on Friday.
Djokovic said he sustained the injury on his right side during a fall in his five-set victory over Taylor Fritz in the third round. The No. 1-ranked Djokovic slipped in the third game of the third set while trying to change directions and he awkwardly went down at the back of the court. He took a medical timeout for treatment from a trainer and was also helped during the next two changeovers.
Djokovic held on to win 7-6 (1), 6-4, 3-6, 4-6, 6-2 over Fritz in an empty Rod Laver Arena.
