Less than a week after claiming a spot in the "So You Think You Can Dance" Top 10, hoofer Jessica King has exited the competition following an injury.

King will be replaced by Comfort Fedoke, the season's most recently eliminated female contestant.

"I would like to say how sorry I am that Jessica cannot continue dancing in the competition at the advice of her doctor," series producer and judge Nigel Lythgoe says in a statement. "Her full recovery is paramount and will only come with rest. We are fortunate that Comfort has agreed to rejoin the competition and know that under the circumstances she has Jessica's full support."

Asked for additional clarification at Monday (July 14) morning Television Critics Association press tour session for the show, Lythgoe was deliberately obscure.

"I'm afraid I can't be specific about the injury," Lythgoe says.

He wouldn't address what the injury was or when it had occurred. He promised that King would give more information on a future show. He would only say that the mystery injury would take up to five weeks to heal.

King had been paired with Will Wingfield for the first leg of the competition. The Top 10 will be swapping partners this week as, for the first time this year, America's votes will be the sole determining factor in who stays and who goes.
