Jankovic, plagued by shoulder and leg injuries throughout the tournament, lost her first service game in the second set before leaving the court to receive treatment on a lower back injury.
The Serbian said she is taking time off tennis to recover from her injuries.
"I will try to recover and get my body back in shape, because I don't like having injuries," the third seed said.
"When you get one injury, it's kind of like a chain. You get so many others because your body is trying to compensate. So I will just try to do my best and see my physios at home and try to recover."
