Two-time Dancing with the Stars professional mirror ball trophy winner Cheryl Burke missed the winter tour's opening night after she experienced pain that required a visit to the hospital, her representative toldE! News on Wednesday.
"Last night, during run-through, I was cramping and in pain," Burke told TV Guide, according to E! News. "I couldn't even stand up straight."
Burke -- who won Dancing with the Stars'second-season title with Drew Lachey and the third-season crown with Emmitt Smith -- was reportedly told she could be suffering from appendicitis. Instead of performing on the tour's Sacramento stop last night, E! News reported the 23-year-old flew home to San Francisco for a second opinion.
"I hope it doesn't require surgery," Burke told TV Guide.
Needless to say, formerDancing with the Stars professional Louis van Amstel -- who is choreographing the tour for the third straight season -- is characterizing Burke's absence from the 37-city North American tour as a "disaster."
"Cheryl can't be gone for more than a week. I won't let her!" van Amstel told TV Guide.
Due to Burke's absence, her partner on the tour -- Lachey -- was instead paired with professional Karina Smirnoff.
"We had a couple of moments when we ran onto the floor at the wrong time, in the wrong place, in the wrong direction," Smirnoff told E! News. "But that won't happen tonight."
