TV actor Gurmeet Choudhary might have to back out of celebrity dance show "Nach Baliye 6" as his wife Debina Bonnerjee has sustained a serious injury on the show.

The TV actress had hurt herself two weeks back, but did not take it seriously.

"Though it was a pull, it turned out to be a cracked rib. It has become worse now," said a source close to the show.

The couple has been performing well on the show and are one of the top contenders of the season.
