If you've been missing who many consider the rock of "Good Morning America," Robin Roberts, hang on for one more week.

Roberts has been off the air for some much needed rest after announcing back in June that she was diagnosed with myelodysplastic syndrome, a rare disease of the blood and bone marrow.

GMA posted on its Facebook page that Roberts will return to the anchor desk August 20, then posted a message from Roberts herself:

"Received a really good report from my doctor today. All my blood counts are up!
The pre-treatment is doing its job and resting as I have lately has helped too. I've been given medical clearance to fly to Tuscany tomorrow for a friend's 50th birthday celebration.

When I return the following week I will have another bone marrow test to finally determine the timing of my transplant. Still slated for the end of the month or early September. That's when my lengthy medical leave will begin.

But all I'm thinking about now is Italy. As a going away present my doctor surprised me and removed my PICC line today from my arm...sweet freedom!

Thank you again for the prayers and well wishes...means more to me than you could possibly ever know.
Ciao! XO"

Roberts will likely have to take more time off leading up to her bone marrow transplant in the future.
