Series executive producer Howard Gordon told a Television Critics Association meeting Tuesday that Cherry Jones was unable to attend a '24' panel because of the surgery. He said Jones was in New York.

A call to her agent regarding her condition was not immediately returned.

Jones, 52, plays President Allison Taylor in the new season of the drama series starring Kiefer Sutherland as a counterterrorism agent. Jones' other credits include the films 'The Village' and 'Ocean's Twelve.' She won two best actress Tonys for 'The Heiress' in 1995 and 'Doubt' in 2005. -- AP
