Talk show host Rosie O'Donnell — who was expected back at work on The Rosie O'Donnell Show today after taking nearly two weeks off to recover from a staph infection to her injured left hand — is taking another week off. "It's too early," her rep tells TV Guide Online. "She's at home resting and will return next Monday." In the meantime, guest hosts will once again pinch hit for the ailing O'Donnell, beginning with funnylady Caroline Rhea today.
