The EastEnders star was eliminated from the contest following a skate-off with Corey Feldman.
Rosemary Conley, Matthew Wolfenden, Jennifer Ellison, Chico, Sébastien Foucan and Sam Nixon earlier made it through based on viewer votes and judges' scores.
In the judges' vote, Louie Spence chose to save Feldman for having given "the strongest overall performance in the skate-off", while Katarina Witt also chose to send home the injury-stricken actress "for the sake of [her] health".
Head panellist Robin Cousins confirmed that he too would have eliminated Morse, telling the 66-year-old: "I admire your courage for having a go, but I'm quite excited to see what we might see from you, Corey."
Morse earlier admitted to hosts Phillip Schofield and Christine Bleakley that she was not disappointed to land in the skate-off, echoing her previous comment to Digital Spy that she was hoping for an early exit.
Dancing on Ice continues next Sunday (January 22) at 6.10pm on ITV1, with all 13 remaining contestants skating together for the first time.
