Novak Djokovic is out of Wimbledon after retiring during his quarter-final against Tomas Berdych with an injury.
The former world number one lost the first set 7-6 (7-2) to the Czech, and was 2-0 down in the second when he had to retire.
Djokovic, 30, had treatment on a right shoulder injury during his last-16 win over Adrian Mannarino and needed further attention against Berdych.
The Serb would have regained the world number one spot had he won Wimbledon.
World number 15 Berdych, the 2010 Wimbledon runner-up, will face Roger Federer in the semi-final.
Djokovic had been set to play his last-16 match against Mannarino on Monday but it was delayed as Rafael Nadal’s match against Gilles Muller went to five sets and tournament officials decided to not move the Serb on to the available Centre Court.
He beat Mannarino 6-2 7-6 (7-5) 6-4 in Tuesday’s opening match but was the only men’s quarter-finalist to not have a day’s rest between matches.
Against Berdych, Djokovic called a medical time out after losing the first set tie-break and received attention on his right arm before he withdrew.
‘No sense’ in continuing – Djokovic
At the post-match news conference, Djokovic said: “It is not the shoulder, it is the elbow that has kept bothering me for over a year and a half.
“It is unfortunate that I had to finish Wimbledon in this way. If someone feels bad, it is me.
“I tried. From yesterday, I tried to get it in the condition where I could play.
“I could play with pain that was bearable for 30 minutes, but the serve and the forehand were shots where I could feel it the most and there was no sense [in continuing].”
