“Good Morning America’s Robin Roberts passed a crucial milestone over the weekend: 100 days since her bone marrow transplant surgery. On Saturday, the GMA anchor Tweeted this photo as she was reunited with her Jack Russell terrier KJ. Doctors advise transplant patients to refrain from coming in contact with pets in the first 100 days as immune systems are still vulnerable. TMZ reports it may be mid-2013 before Roberts is healthy enough to return to the show. But an ABC News spokesperson says, “We have never put a timetable on Robin’s return. We have always said that the decision will be made by her doctors when they feel it is the right time.”
