As we already said, Jelena got an injury during her practice on Friday morning and that was why she skipped the Opening Ceremony. But more bad news. She will maybe pull out of the Olympic Games.

JJ appered at at a press conference with her right leg strapped and said she wouldn't risk aggravating the problem.

"I'll practise today and I'll see tomorrow how everything goes," she said.

"If I can't play, if I'm not going to be able to give my best on the court, I will not go. It's not a risk I will take."

Jelena said she damaged her calf by over-compensating while recovering from a serious left knee problem.

"Because I had an injury on my left knee, my right leg was working so much harder," she said. "It was compensating. I was forcing the other muscles to work harder."

Jelena is due to play Zimbabwe's Cara Black in the first round.

"Hopefully I will somehow be healthy and ready to play my best tennis," Jankovic said Saturday.
