LONDON: Novak Djokovic said a right elbow injury was to blame for his retirement from Wednesday's Wimbledon quarter-final against Tomas Berdych.
Djokovic needed treatment on his elbow at the end of the first set and was already dealing with a long-term right shoulder problem.
The three-time Wimbledon champion, who would have regained the world number one ranking if he had won the tournament, was trailing 7-6 (7/2), 2-0 when he called it quits on Court One.
"I started feeling it at the beginning of the tournament. The level of pain was always increasing and today was the worst day.
"I tried what I could do to get it in condition to be able to play.
"All the treatments couldn't really help. The serve and forehand were the shots I could feel it most."
