Robin Roberts won't be back until May

NEW YORK, Dec. 30 (UPI) —

Robin Roberts will not return to "Good Morning America" until May at the earliest, TMZ reported.

Roberts, 52, is a breast cancer survivor who underwent a bone-marrow transplant to treat the rare blood disorder, myelodysplastic syndrome, in September. She has been recuperating since.

TMZ said "GMA" producers hoped she would be able to return in February, but her doctors don’t think she will be strong enough to do so until at least May, but more likely June.
