Who says ballroom dancing is not brutal on the body? Just ask Chilean film star Cristian de la Fuente, who injured his arm Monday night on the popular U.S. TV show “Dancing With the Stars.”

De la Fuente, who gained fame on Spanish-language television and has guest-starred on U.S. TV on progams such as “CSI: Miami” and “Ugly Betty,” was finishing a saucy latin spin around the dance floor Monday night when he could no longer hold his pose with professional ballroom dancer Cheryl Burke. His arm seemingly cramped up, and after an impromptu commercial break on the live TV show, de la Fuente returned to the stage  grimacing in pain with his arm bandaged.

On Tuesday, a spokeswoman for the actor said he was seeing a doctor in Los Angeles, but would appear again on Tuesday’s episode of “Dancing With the Stars.” She said she did not know exactly what the medical problem was, adding that his condition would be fully revealed on the show Tuesday night.

It is not the first time a “Dancing With the Stars” contestant has been stricken on live TV. Last season, entertainer Marie Osmond fainted after one number, but popped back to her feet following a commercial break. Also this season, professional dancer Derek Hough, who is partnered with actress Shannon Elizabeth, hurt his neck in rehearsal and had to be taken to a hospital.

One lesson: If you gotta dance, get a medical check-up first.
