4minute's HyunA wowed her fans after they discovered she performed on "Dancing With The Stars" with an ankle injury. The star reportedly sustained the injury while rehearsing at an SBS special concert, and was required to put on a cast. But HyunA was determined to make a good impression on the show, and so she not only performed the full choreography for her routine, but did so without the cast. Her effort seems to have paid off, as she lived up to her title of being the most anticipated female dancer on the show.� She also never talked about her injury on air, and people weren't able to catch that she was injured at all due to her fantastic performance. Unfortunately, HyunA must keep the cast on for the next two to three weeks. Cube Entertainment commented, "We are continuing treatment in case her injury gets worse. She has a lot of determination to do well, so she will be doing her best for all of her future performances." Source + Photos: OSEN via Nate
