The reality TV star was injured during rehearsals and was taken to a Los Angeles hospital for tests.
She was later released after she was examined and bravely returned to the show on Monday night with her dance partner Tony Dovolani to perform for the judges.
She told the audience that she had a herniated disc in her neck, adding, “I’m on a little medication right now. (But) I’m officially cleared to dance.”
And despite her health scare, Rycroft received rave reviews from the panel after performing a freestyle dance with the rest of her group partners.
