Lindsey Vonn says she will undergo tests on both knees after a grueling World Cup season in which she recaptured the overall title.

The Olympic gold medallist was bothered by her aching knees during the season, but elected to keep it hidden. She said on Saturday after skiing out in the giant slalom at the U.S. championships that an initial checkup indicated probable trouble in both knees. She's scheduled for an exam on Monday.

Vonn doesn't think the injury will be "too big of a deal" and hopes the injury "won't set me back too far."

It was quite a season for Vonn, who amassed the most points ever by a female skier. She was chasing Hermann Maier's record mark of 2,000 points, but finished shy at 1,980.
