Mark Harmon isn't going anywhere.
On Thursday, the actor's rep shot down a report that Mark is leaving "NCIS," telling Page Six the rumor "is completely false."
Hours earlier, Celebrity Insider reported that Mark, 67, is considering leaving the hugely popular show due to "failing health."
Last year, Mark had knee surgery and, Celebrity Insider reports, "rumors have been circulating that his health issues are back."
Mark, who remains one of the highest-paid actors on television, has starred on the long-running CBS series since it debuted in 2003, and he serves as an executive producer on both "NCIS" and "NCIS: New Orleans."
The main cast of "NCIS" has remained largely in tact for the majority of the show's run. The last major star to depart was Pauley Perrette, who starred on the series for 15 seasons.
Celebrity Insider also claimed on Wednesday that David McCallum, who plays Donald "Ducky" Mallard, is contemplating leaving the show, citing his lower workload during the current season.
