Lindsey Vonn re-injured her right knee during a training run Tuesday, jeopardizing her hopes for competing in the 2014 Winter Games in Sochi.

"Lindsey sustained a mild strain to her right knee, a partial tear to her right ACL, minor facial abrasions and scapular contusions from her fall," publicist Lewis Kay said in a statement. "She needs to rest for a few days and then will pursue aggressive physical therapy and will determine the next time she is able to compete after seeing how she responds to the treatment."

Vonn was taken off the slopes of Copper Mountain, Colorado on a sled, a standard precautionary measure. One observer on Twitter offered up what was purported to be a shot of Vonn on her feet following the wreck:

Ski Racing magazine first reported the accident, which is a severe setback in her rehab from an earlier wreck. In February, Vonn tore the ACL and MCL in her right knee and suffered a broken leg when her legs became entangled in a wreck during the super-G at Schladming, Austria.

Though her return in time for Sochi was in doubt then, Vonn recently said she felt 100 percent. She was back on skis for the first time on Aug. 31, according to USA Today, and just last week began downhill training for the first time since the injury. Vonn was scheduled to race in three World Cup events at Beaver Creek, Colo. immediately after Thanksgiving, then onto Sochi. Vonn won gold in the women's downhill at the 2010 Games.

There are no actual trials to qualify for the Olympic alpine ski team. Roster spots are based on "objective criteria, generally through rankings and results in the FIS Alpine World Cup tour." According to criteria established by the United States Ski and Snowboard Association, some roster spots "will be filled at the discretion of the coaching staff," meaning Vonn could still be named to the team.

Back in February on the Today Show, Vonn said "in a worst-case scenario, if I trained a week before the Games, I’d be fine." The women's downhill in Sochi is scheduled for Feb. 12, 85 days from the date of Vonn's latest setback.
