Supporters from across the globe have rallied behind a US athlete who suffered a horror injury during her floor routine at an NCAA gymnastics regional event.
Auburn University student Sam Cerio was attempting a handspring double front with a blind landing when she made the hard landing and fell to the mat at the Baton Rouge Regionals at the weekend.
She dislocated both of her knees and broke both of her legs - and was left screaming in agony on the floor as teammates and officials rushed to her aid.
The New York Post reported Cerio had air casts around both her legs and was carried on a stretcher from the venue - to a standing ovation.
