Robin Roberts' 'GMA' Return Date: Feb. 20

Robin Roberts is returning to "Good Morning America" on Feb. 20th, ABC News announced Thursday morning.

Roberts has not been co-hosting the show since August 30, when she left to begin treatment for the rare blood disorder MDS. Since then, she has had a bone marrow transplant and has been in intensive recovery.

Roberts shared the news in a blog post:

After seeing my doctor again this week I now know when I can return to the anchor chair. February 20th, which will be exactly 5 months since my bone marrow transplant.

I'm excited to re-join my wonderful 'GMA' family. I'm also looking forward to thanking YOU ... for your many prayers and well wishes. Your compassion has been an enormous source of comfort to me and my family.

I'm heading to the beach for the next week to reflect and give thanks for my many blessings.

"GMA" weatherman Sam Champion said Roberts will not host every day right away.

In January, Roberts made the surprise announcement that she would be returning to the show soon. She made a trip to the "GMA" set later that month, to see how her body could cope with interacting with so many people. That experiment was evidently successful.

"GMA" has also maintained its ratings lead over "Today" throughout Roberts' long absence, despite some recent losses in the A25-54 demo.
