MOODY MARK BAILS ON NCIS!

Why TV lawman is done after 18 years

A GING Mark Harmon quit NCIS after 18 seasons because the 70-year-old former college football star couldn’t take the brutal wear and tear on his bod and the daily grind was turning him into a moody monster, insiders dish.

On the Oct. 11 episode, Harmon’s beloved character, Special Agent Leroy Jethro Gibbs, bids farewell to the NCIS team after solving a case in Alaska.

“I’m not going back, Tim,” Gibbs tells his partner and NCIS Director Leon Vance.

When asked what he hoped to find in Alaska, Gibbs replies, “I don’t know. My gut’s telling me I’ll know when I find it.”
