Cibulkova said the injury has been bothering her all week.
“It was painful when I played Marina (Erakovic), but I was able to get through that match,” she said. “I thought it would be better in the morning, but I saw a doctor and he recommended not playing since the injury could worsen.”
Cibulkova had the same problem earlier in the year, missing two tournaments after getting through the quarterfinal at Madrid.
“Maybe I rushed to play too quick,” she said. “I don’t want to make the same mistake.”
Cibulkova still plans to travel to San Diego, where she is scheduled to play Wednesday.
“It’s still open and I’m hoping to be ready,” she said. “I still have things to do in San Diego.”
“It was a great tournament for me,” Cibulkova said. “I was looking forward to maybe winning my first tournament. I was so full of confidence.”
The ninth-ranked Bartoli reached her fourth final of the year and her third final at Stanford. She won the title in 2009. Bartoli reached the semis when Japan’s Ayumi Morita withdrew with an injury after the first set Friday night.
