Two-time CrossFit Games champion Annie Thorisdottir has injured her back and “definitely won’t participate in the Open” she told CrossFit Media Thursday afternoon. 

On Wednesday, she posted on her Facebook fan page that she hurt her back again. 

“Not sure how big of a (setback) this means.  It is not as bad as last time, but slightly herniated disc. ( Cannot) even try to express how disappointed and angry I am at myself, but things happen,” the 23-year-old wrote in a status update. “ I will keep you updated.  Thank you everyone for the support!” 

On Thursday Thorisdottir went on to say, “I can’t even do an air squat.” 

The coach at Iceland’s CrossFit Reykjavik is the first woman to win the Games twice. 

Before qualifying for her first Games in 2009 in Aromas, Calif., Thorisdottir only had been CrossFitting for about a month.  During the competition, she performed a GHD sit-up and a muscle-up for the first time.  She finished 11th overall with a DNF on the final workout. 

In 2010, Thorisdottir placed second at the Games, which were held for the first time at the Home Depot Center in Carson, Calif. She went on to win the Games the next two years. 

“It was the most amazing feeling ever,” Thorisdottir said in August of winning again. “ It was seriously cool.” 

Thus far, Thorisdottir has completed the Open’s first three workouts.  She reported 209 reps for 13.1, 361 reps for 13.2 and 259 reps for 13.3, which put her in 12th worldwide.  Director of the Games Dave Castro announced workout 13.4 Wednesday night.
