The 11-year-old actress who starred as Nala in the Broadway hit “The Lion King” has undergone a potentially lifesaving procedure.

Shannon Tavarez, who has leukemia, received an umbilical-cord blood transplant yesterday at Long Island Jewish Hospital.

The procedure was performed as an alternative to a bone-marrow transplant. Her doctor said a perfect bone-marrow match for her could not be found.

A family friend said Shannon will remain in the hospital under observation for doctors to ensure that her body does not reject the transplant.

She was forced to quit the show in April. Cast members held a marrow-donor registration drive for her last month.
