After being seriously injured in a crash during the Alpine World Championships, skier Lindsey Vonn flew home to the United States on Friday in a private jet provided by Tiger Woods, according to TMZ.com. 
The gossip website ran a photo it said was of Vonn on crutches boarding the plane. There was no indication of where the plane was headed, though speculation was its destination was Colorado, where Vonn lives.
Vonn, by far America's most prominent and successful ski racer these days, was airlifted to a hospital last Tuesday after she crashed during a Super G event, tearing two ligaments in her right knee and fracturing her shin.
Woods and Vonn have been rumored to be dating for several months, though neither has said anything about a possible romantic relationship between the two recently divorced superstars. Last December, Vonn told The Denver Post  that she met Woods after her brother taught Woods' children how to ski in Vail, Colo., and they are ''just friends.''
In January, the Salzburg Times newspaper  reported that Woods and Vonn are dating, and said that Woods stopped in Salzburg on his way to the Abu Dhabi HSBC Golf Championship in mid-January at the same time Vonn was in Salzburg. The paper also showed photos of Woods, wearing a Nike sweatshirt and New York Yankees baseball cap, on what it called a ''short visit'' to Salzburg.
Meanwhile, Vonn soon will have surgery on her right knee, and says she hopes to return to competition in time for the 2014 Winter Olympics in Russia. Woods is next scheduled to play at the WGC-Accenture Match Play Championships in Marana, Ariz., the week after next.
