Welsh mezzo-soprano Katherine Jenkins, like many ballroom contestants before her, was injured on the set of "Dancing With the Stars."
Fans could see Jenkins in tears after freezing up in pain during a back-bend dance move on national TV in May 2012. She'd suffered a spasm in her lower back at the end of her vigorous Arabian-themed salsa.
Season 14 costar Melissa Gilbert was also hospitalized that same season for a mild concussion and whiplash she sustained on the set. Maria Menounos broke two ribs and William Levy injured his ankle. And that's all in just one season.Stuart Wilson / Getty Images
