THOUSAND OAKS - Tiger Woods isn't booking his tickets to the Sochi Olympics just yet, even though girlfriend Lindsey Vonn says she thinks her injured left knee will let her defend her downhill crown.
"It's day to day," Woods said Wednesday when asked if he planned to attend the Winter Games in February. "We just don't know how her leg is going to be."
Vonn partially tore a ligament in her surgically rebuilt right knee in training two weeks ago.
That forced her out of World Cup races in Beaver Creek, where she was slated to return to competition for the first time since crashing at the World Championships in February.
On Wednesday, the US ski star clocked the 22nd-fastest time in a World Cup downhill training run at Lake Louise, Canada, where she is a 14-time winner.
"Back in one of my favorite places -- Lake Louise!!" Vonn posted on her Instagram page with a photo of her on the Canadian slope.
Vonn, 29, is an inveterate user of such social networking sights as Instagram and Twitter.
Woods, who will turn 38 on December 30, says Vonn has encouraged him to tweet more, but his offerings to his millions of Twitter followers remain sparse.
"She certainly has hinted that, but I grew up in a different era and it's a little bit different for me," he said. "I'm still a little bit old school. I'm kind of getting towards it, but still not quite grasping the whole concept yet.
"But I'll get there eventually."
