The mystery over Tiger Woods' car crash intensified yeserday when his agent called state troopers on their way to Woods' house in Windermere, Fla., and asked them to wait another day before speaking to him.

It was the second day in a row Woods was unavailable to talk. His wife told troopers Friday afternoon, after the world's No. 1 golfer had been treated and released from a hospital, that he was sleeping and asked that they return yesterday.

Woods is not required by law to speak to the Florida Highway Patrol because it is being investigated as a traffic accident.

Woods was injured when his Cadillac SUV struck a fire hydrant and a tree just beyond his driveway at 2:25 a.m. Friday. Police said his lips were cut and blood was in his mouth when officers arrived. Police said Woods' wife, Elin, smashed the back window with a golf club to help get him out.

Troopers were en route to Woods' $2.4 million mansion in the gated community of Isleworth when agent Mark Steinberg called dispatch and was put through to the troopers, telling them Woods and his wife were unavailable.

Steinberg also was unavailable to comment.

With so many questions lingering -- where was he going at that hour -- and rumors circulating on the Internet, one marketing expert said silence was only stirring the pot.

More than two dozen media and a cluster of TV trucks were camped outside the gates of Isleworth, an exclusive subdivision near Orlando that's set on an Arnold Palmer-designed golf course and a chain of small lakes watching for any developments. Even a couple of tourists stopped by and took pictures.

Woods' news conference for the Chevron World Challenge, the tournament in which he is the host that benefits his foundation, had been scheduled for Tuesday. It's unclear whether he would still play, or even attend the event in Thousand Oaks, Calif.
