Rafael Nadal's Australian Open campaign came to a hugely disappointing end in just the second round, sparking concerns regarding his future.
The Spaniard succumbed to a 6-4, 6-4, 7-5 defeat against USA's Mackenzie McDonald - his earliest exit at Melbourne Park since an opening round loss in 2016. The 36-year-old has struggled with injury over the past six months and this time a hip problem scuppered his chances of playing his best tennis.
Nadal was running out wide to hit a forehand when he appeared to jar his left hip, immediately touching the area and dropping to his haunches. The top seed limped through the rest of the game and then left court for a medical timeout, returning to see out the second set.
