Tierney, who just ended her 10-year stint as a doctor on ER, was supposed to begin filming Parenthood, which is a contemporary look at the 1989 film of the same name, on July 27. The show revolves around four siblings — Tierney, Peter Krause, Erika Christensen and Dax Shepard — and their parents. The series was scheduled to premiere Sept. 23. "Due to these circumstances, NBC's new drama series Mercy will premiere in the fall," NBC's rep told Us. "Details on changes to NBC's fall premiere dates will be forthcoming."

This isn't the first time filming on Parenthood has been put on hold. In April, production on the pilot was shut down for two days after NBC's VP Nora O'Brien died unexpectedly on the Berkeley, Calif., set of the show.
