The reality TV star was injured while practicing for Monday night's group number. She was taken to the hospital Sunday, but has since been released.
Rycroft was diagnosed with a disc herniation at the C4-C5 level of her cervical spine, according to ABC spokesman Danielle Valparaiso.
She was scheduled to perform Monday, when four couples take the dance floor, but due to her injury, it was not yet known if she will dance. The decision will be made at show time, Valparaiso said.
On Tuesday, the remaining four will perform. No one will be eliminated until next week.
