The medical problem is not considered serious, and the disruption to 24 is expected to be brief.
"We are temporarily suspending production of 24 while our friend and colleague Kiefer Sutherland undergoes a medical procedure," the network says in a statement. "We hope to resume production shortly and do not anticipate any disruption in the broadcast of this season's episodes."
A rep for Sutherland says: "While Kiefer Sutherland is frustrated to miss even one day of work, he and FOX decided together that it would be best to complete this minor elective procedure now as a precaution as opposed to six weeks from now when production wraps. He looks forward to returning to work (this) week."
