May 5 (UPI) -- David McCallum announced on Facebook he has signed on for another season of "NCIS."
"I am delighted to say that I have reached an agreement with CBS for Dr. Donald Mallard to stay with NCIS for Season 16. Once again it will be a limited schedule. That arrangement will allow me to spend time with Katherine, our children, six grandsons and Nickie, pictured below!" the actor wrote in a post this week.
The message included a photo of his pet cat.
McCallum, 84, has played medical examiner Mallard since the show began in 2013. CBS announced last month it had renewed the procedural for the 2018-19 television season, with McCallum's co-star, Mark Harmon, set to return.
