The new NBC drama “Parenthood” has been pushed to midseason due to star Maura Tierney’s unspecified illness. Here’s hoping all is well with Tierney, who is currently undergoing a medical evaluation.

NBC announced that production on Parenthood has been postponed eight weeks, “due to medical evaluation that (Tierney) is undergoing. We are unable to release further details and ask that you respect her privacy at this time.”

Parenthood, based on the 1989 film, had been scheduled to begin filming in late July – now it will begin in late September.

Parenthood, starring Peter Krause, Tierney, Erika Christensen and Dax Shepard as siblings in various stages of family relationships, had been slated for a September 23 premiere. Check out the sneak peek video for what looks to be a very good dramatic series.

Parenthood will now begin mid-season on NBC.
