Lindsey Vonn is skipping a women's World Cup night slalom on Tuesday because of a lack of recent training in the discipline.

Vonn, the defending overall champion, was missing from the list of 68 competitors published by governing body FIS on Monday.

"It's her goal to race where she has the chance to win," U.S. women's head coach Alex Hoedlmoser said. "And without any slalom training, there is no chance to win a slalom."

Vonn has now missed out on all six slalom events this season.

In mid-December, she took a break from skiing to recover from intestinal illness. The American returned for speed races in St. Anton, Austria, last weekend, placing sixth in downhill and fourth in super-G.

After Sunday's race, Vonn said she had yet to decide on competing in the Flachau event, where she finished eighth last season.

Hoedlmoser said Vonn is now fully focusing on speed races in Cortina d'Ampezzo, Italy, this weekend.

"It's a logical step," Hoedlmoser said. "There was not enough time in the period where she was gone and did the physical training, to prepare for a slalom."

Vonn, who trails overall leader Tina Maze of Slovenia by 785 points, said Sunday she had put the defence of her title out of her head.

"(Maze) had the overall title a few weeks ago already," Vonn said. "When I decided to take a break I knew that I would most likely lose the overall title."

In recent years, slalom has become Vonn's least successful discipline. She won two races in the 2008-09 season but has not finished on the podium since placing second in Levi, Finland, in November 2009.
