Lindsey Vonn will have the chance at a third victory at this year's world alpine ski championships, despite an injured thumb.

The American skier proclaimed herself ready for Saturday's women's slalom in Val d'Isere, France, after testing out her grip during training runs on Friday.

"She's going to go. She did three or four runs and it was actually quite good," U.S. women's head coach Jim Tracy said. "She wants to race and she did what she needed to do to be ready."

The slalom is the final women's event at the world championships. The race can be seen live on bold and CBCSports.ca (3:55 a.m. ET) and later on CBC Television (3 p.m. ET).

She missed Thursday's giant slalom and spent two days testing out a specially designed splint that will enable her to hold her ski pole.

Vonn sliced her thumb on a broken champagne bottle following Monday's downhill victory. She needed four stitches to close the wound and travelled to Innsbruck, Austria, on Wednesday for surgery to repair a severed tendon.

Vonn, who won the super-G event on Feb. 3, couldn't get the champagne bottle open after her downhill win because the cork broke.

Someone then used a ski to get the remaining part of the cork out, cutting the bottle in the process. However, Vonn grabbed the bottle as the champagne poured out, not realizing her thumb was cut.

Meanwhile, the slalom will mark the return of American Resi Stiegler after a 13-month injury layoff. She posted three top-10 finishes in slalom last season before crashing in giant slalom in Lienz, Austria.

She fractured her left arm, had ligament damage to her right knee and multiple bruises. Stiegler began training full time last month in Kirchberg, Austria.

"There's no expectations," Tracy said. "It just turns out that her first race back is going to be at world championships."
