Nine-time Australian Open champion Novak Djokovic reportedly cut short a practice match against Daniil Medvedev Wednesday because of a left hamstring issue, five days before the Grand Slam.
The Serbian superstar is back in Melbourne after his deportation last year but required treatment and then ended the knock-about with the Russian after losing the first set.
The session at Melbourne Park was supposed to last 75 minutes but was instead curtailed after just over half an hour as a precaution, the ABC and 9News Melbourne reported.
"It's the hamstring that I had problems with in Adelaide last week," Djokovic said, according to 9News.
"I just felt it pulling and I didn't want to risk anything worse. I played a set and apologized to him (Medvedev) and he was understanding.
"I just want to avoid any bigger scares before the Australian Open," he said.
Djokovic, who won the Adelaide crown on Sunday despite the lingering hamstring issue, is hot favorite to triumph in Melbourne once again.
The 35-year old is supposed to play Nicholas Kyrgios in a re-run of last year's Wimbledon final Friday in front of a full house at Rod Laver Arena in another practice match.
Djokovic, one of the finest men's tennis players of all time with 21 major crowns, was deported from Australia a year ago over his stance on Covid vaccines.
