U.S. and Jewish gold medalist Aly Raisman was injured during a gymnastics performance on Sunday in California.

On tour with her teammates from the London Olympics, Raisman suffered two bruised knees during a show in Ontario, CA, on the  Kellogg’s Tour of Gymnastics.  McKayla Maroney, who was also performing injured her left knee as well, and tests are being done to determine the extent of the injury.

Following her injury, which occurred after she lost her grip on the bars while performing a Shaposhnikova move, Raisman was able to get up and re-join the show.

“Raisman, who was examined at the arena by the physician for the performance, has bruised knees,” USA Gymnastics said in a statement on its website.  “She will follow an icing and additional treatment regimen with continued assessment by the medical staff, but does not require any further testing at this time.”

A woman in attendance took to her Tumblr page to describe the account.

“So there are two uneven bars set up and each of the girls are doing little mini routines.  They’re all doing it simultaneously, and every time one girl dismounted from the bars the next one was right up there doing their thing.  I looked over just when McKayla landed (feet apart and sort of crouched if I recall correctly) and she either fell right after she landed or took a hop and then fell.  Either way she was on the ground and she wasn’t really getting back up.  Aly (who was preparing for her turn on bars) came over to see if she was ok.  Two medics noticed that Mack was down so they came running over, she must have said she was hurt because they both picked her up between them and carried her out of the arena.”
