It was simply the need for more training after a hectic qualifying schedule that included the ankle injury and a nasty fall in a slopestyle qualifier in Mammoth Lakes, Calif.
Despite all that, White qualified for both events and will have a chance to win a third gold medal in halfpipe and take the first ever awarded in slopestyle.
White will spend a few days at home before heading to Germany, where the U.S. Olympic Committee will give athletes final paperwork and instructions before sending them on charter flights to Sochi.
Slopestyle training starts Feb. 3, with the competition beginning three days later.
The halfpipe contest is Feb. 11.
Asked about White's overall health, Keene didn't hesitate: "He's 110 percent."
