Cheryl Burke off Dancing tour after being hospitalized for possible appendicitis

The Dancing with the Stars 5 national tour started Tuesday night in Seattle, but two-time winner Cheryl Burke was not there due to illness, and may not return for some time.

“Last night [Monday], during the run-through, I was cramping and in pain. I couldn’t even stand up straight,” Cheryl told TV Guide. The magazine reports that she “was rushed to the hospital, [and] was told that it is a possible case of appendicitis. She will fly home to San Francisco on Wednesday for a second opinion from her family doctors.”

She’s not the only absent pro dancer; Mark Ballas “is recovering from a dislocated left arm and won’t be able to join the tour until after Christmas, possibly in San Diego on Dec. 27,” TV Guide reports.

Mark’s partner (and romantic interest) Sabrina Bryan is dancing with Derek Hough instead, while Karina Smirnoff is taking Cheryl’s place with Drew Lachey. Fellow dancer and tour choreographer Louis van Amstel said Cheryl’s absence is “a disaster,” while Karina says she wants Cheryl back ASAP. “Cheryl can’t be gone for more than a week,” she said. “I won’t let her!”
