Good Morning America Co-Host Robin Roberts will return to the show Feb. 20

NEW YORK - Good Morning America co-host Robin Roberts made a special announcement Thursday morning -- she'll return to GMA on Feb. 20.

That's five months to the day since she underwent a bone marrow transplant to treat Myelodysplastic Syndrome or MDS, a rare blood disorder. Roberts received a bone marrow transplant from her sister Sally-Ann and has since been recovering at home.

Last month Roberts made a live appearance on GMA from her New York City home. She announced her plans to return to the set sometime this month.

Roberts has been going through dry runs on the GMA set and readjusting to her old surroundings.

Rpberts will work a modified schedule until she is ready to return five days a week.

A special edition of 20/20 on Feb. 22 will offer a behind-the-scenes look at Roberts's experience and those who have been inspired by her example.
