Nastia Liukin, an Olympic gold medalist gymnast, and her dance partner, Derek Hough, were eliminated during week nine of season 20 of "Dancing With The Stars." On "Dancing With The Stars," a reality show, celebrities pair up with professional dancers. The couples compete against each other in several types of dance.
Week nine marked the semi-finals of Season 20 of "Dancing With The Stars." Even though Liukin received perfect scores from the judges for her two dances that week, a Quickstep and a Viennese Waltz, she and Hough were eliminated during the Results Show.
Hough suffered injuries to both of his feet during week seven of Season 20, forcing Liukin to train and perform some of her numbers with another professional dancer, Sasha Farber.
