Novak Djokovic posted a scan of his injured left hamstring on social media early Sunday, more than 24 hours after being booed at the Australian Open when he quit playing one set into his semifinal because of what he said at his news conference was a torn muscle.

Novak Djokovic's bid for a record 25th Grand Slam singles title came to an abrupt end Friday at the Australian Open when the 37-year-old legend had to retire from his semifinal against Alexander Zverev after just one set due to injury.
