Defending champion Novak Djokovic is unsure if he will be able to play in the fourth round of the Australian Open after he survived an injury scare to battle past American Taylor Fritz.
World number one Djokovic was hampered by a side injury that restricted his movement, although he still recorded a 7-6 (7-1) 6-4 3-6 4-6 6-2 victory.
Djokovic is set to meet 14th seed Milos Raonic in the next round.
The Serb, who is chasing a record-extending ninth men's singles title in Melbourne and a third in a row says this is one of the most special wins in his life.
Djokovic hobbled between points, clutched his side and received medical treatment, but 23-year-old Fritz, the 27th seed, could not take advantage.
The match was the final one to be played on Rod Laver Arena on day five of the tournament and began with a crowd of up to 8,000 people in attendance at the beginning.
