Beijing:Incoming world number one Jelena Jankovic on Saturday admitted she was in doubt for the Beijing Olympics after picking up a calf strain.
Jankovic, who will reach the top ranking on Monday despite an injury-hit season, appeared 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."
The 23-year-old Jankovic said she damaged her calf by over-compensating while recovering from a serious left knee problem.
Jankovic, who is set to replace fellow Serb Ana Ivanovic as world number one, is due to play Zimbabwe's Cara Black in the first round.
