This image released by ABC shows "Good Morning America" co-host Robin Roberts, center, poses with her sister Sally-Ann Roberts, left, and Dr. Gail Roboz on the popular morning show on Thursday, Aug. 30, 2012 in New York. Roberts has said goodbye to "Good Morning America," but only for a while. The "GMA" anchor made her final appearance Thursday before going on medical leave for a bone marrow transplant. Roberts' departure was first planned for Friday, but she chose to exit a day early to visit her ailing mother in Mississippi. In July she first disclosed that she has MDS, a blood and bone marrow disease. She will be hospitalized next week to prepare for the transplant. The donor will be her older sister, Sally-Ann Roberts. Roboz, who is helping Robin prepare her for her bone marrow transplant, appeared on the program to discuss the medical road ahead. In the coming weeks, Dr. Roboz will help monitor Robin’s health and progress. (AP Photo/ABC, Fred Lee) less
