Kirstie Alley was accidentally dropped her partner, professional dancer Maksim Chmerkovskiy on "Dancing with the Stars" in Los Angeles.
They quickly recovered and completed the routine.
"My thigh just gave out. I'm so sorry. I'm so sorry," Chmerkovskiy said later. "It has nothing to do with her."
The judges awarded them 21 out of 30 points and praised them for their fortitude, People.com said.
"You've overcome it," said judge Len Goodman. "You got up and dusted yourself off."
"You can't keep good talent down. Once you got up it was better than ever," added Bruno Tonioli.
Alley, an actress, is best known for her work in the sitcom "Cheers," as well as the "Look Who's Talking" series of films.
