If anyone is wondering why I didn't compete in the Olympics a few days ago, here is why. Dislocated shoulder in second run of practice. #teamusa Posted by Arielle Gold on Saturday, February 15, 2014

KRASNAYA POLYANA, Russia – American snowboarder Arielle Gold was unable to compete in qualification for the Olympic halfpipe finals on Wednesday because of a shoulder injury she suffered in training moments before the competition.

Now we see why.

In a video on Gold’s Facebook page, she is shown landing a 720 on the lower portion of the pipe before her board gets caught on something in the flat bottom and she tumbles face first.

She attended the final to support her American teammates, but appeared to have her arm in a sling under her jacket. Gold, 17, was considered a medal contender.

Americans Kaitlyn Farrington and Kelly Clark took gold and bronze, respectively, in her absence.

Riders voiced concerns about the condition of the pipe throughout the three days of training leading up to the men’s competition on Tuesday. The men competing that night said the pipe had improved since they started training on it but that there were still some issues they had to work around.
