Djokovic in Madrid Open semis; Cilic ill
World No.1 Novak Djokovic automatically progressed to the Madrid Open semi-finals after his quarter-final opponent Marin Cilic was forced to withdraw because of food poisoning on Friday.
"Dear fans, Madrid Open organisers, Novak Djokovic, I am sorry to announce that I must withdraw from today's match," said the Croatian via Twitter.
"I have had a terrible night dealing with a case of food poisoning. I am extremely disappointed to have my time in Madrid end in this way. Thank you for the support."
Djokovic, in his 250th week at the top of the men's ATP rankings, will face either Roger Federer or Dominic Thiem in the semi-final on Saturday.
The Serbian, who triumphed in the Spanish capital in 2011 and 2016, beat Taylor Fritz and Jeremy Chardy in the second and third rounds.
Earlier, Dominic Thiem also progressed to a quarter-final with world No.3 Roger Federer thanks to a 6-4 7-5 win over Australian John Millman's conqueror Fabio Fognini of Italy.
Federer survived two match points against French maverick Gael Monfils to extend his clay-court comeback.
The evergreen 37-year-old did not drop a game in a dominant first set but was dragged into an intense battle by an inspired Monfils before prevailing 6-0 4-6 7-6 (7-3).
