VAL D'ISERE, France -- Lindsey Vonn pulled out of a World Cup super-G race on Sunday because of a sore knee.
The 33-year-old American did not say which knee hurts, but has injured both before.
She took part in Sunday's early-morning inspection at the French Alpine resort, but then decided against racing as a precautionary measure and flew home.
Vonn secured her first win of the season and record-extending 78th in Saturday's super-G on the same Oreiller-Killy course.
Last weekend, she jarred her back in another super-G race at St. Moritz in Switzerland.
Her focus is on the Pyeongchang Olympics in South Korea from Feb. 9-25. She won gold in downhill and bronze in super-G at the 2010 Games.
Vonn has battled with injury during her illustrious career.
She sustained a hairline fracture to her left knee in a super-G race in February 2016.
At the 2013 world championships, Vonn crashed in the super-G and tore ligaments in her right knee. She was unable to defend her Olympic title at the 2014 Games.
