Pop star Jewel and TV host Nancy O'Dell have dropped "Dancing With the Stars."

Both women sustained injuries during training for the show that prevent them from continuing the competition, the network announced Thursday. Jewel was diagnosed with a fractured tibia in both legs, while the "Access Hollywood" host will need surgery to repair a torn knee cartilage, the network said.

A replacement for at least one of the women may be announced during tonight's season premiere, said executive producer Conrad Green.

"Obviously this has caught us a bit by surprise," he said, adding that any replacement would have "literally a couple of days to learn the routine, as opposed to a month."

"The show will go on," Green said. "But really, our thoughts are with Jewel and Nancy. It's such a tough blow for them and just horribly bad luck."

Jewel and O'Dell are the first contestants in eight seasons of "Dancing" to withdraw because of injuries sustained during pre-show training, Green said. Olympian Misty May dropped out last season after tearing her Achilles tendon during the competition.
