TV chiefs have halted production of the thriller 24 so its star Kiefer Sutherland can undergo surgery.
Shooting is expected to resume next week with Sutherland's return.
Twentieth Century Fox Television would not comment on the nature of Sutherland's ailment, referring to it only as "a medical procedure".
The Los Angeles Times first reported the production halt and said Sutherland, who is also 24's executive producer, was suffering from a ruptured cyst.
Sutherland plays counter-terrorist hero Jack Bauer on the series. The show is now in its eighth season.Reuse content
