People.com: Jilted by Jason Mesnick on the season finale of The Bachelor, Melissa Rycroft will rebound nicely -- on Dancing With the Stars, PEOPLE has learned.

Rycroft, 25, is to fill the slot vacated by Access Hollywood host Nancy O'Dell, who had to withdraw from the competition on March 5 due to a knee injury. According to a source close to the production, the Dallas beauty, who has had only days to rehearse, is expected to perform live on Dancing's Monday premiere.

Girl Next Door Holly Madison is believed to be taking over for singer Jewel, who also withdrew due to injury. Both Jewel and O'Dell have expressed their desire to return to the ballroom in the future.

A spokesperson for ABC declined to comment.
