Former cast regulars Mark Valley and Rene Auberjonois are slated to return for multiple episodes for the series' fourth season, Hollywood Reporter said Monday. Saffron Burrows and Gail O'Grady also will have multi-episode storylines.
ABC last month announced options on four regulars -- Valley, Auberjonois, Julie Bowen and Constance Zimmer -- were not renewed. The alphabet network also announced Emmy winner John Larroquette and Tara Summers would join the show as regulars and Christian Clemenson's recurring role would become a regular one.
