Robert Wagner and Ralph Waite, two NCIS fan favorites as the fathers of DiNozzo and Gibbs, respectively, will be reprising their roles this season, EW reports.

Wagner, 81, has made memorable appearances in each of the last two seasons of NCIS, while Waite, 83, has guest starred in each of the previous three.

It's not clear if one or both will appear on the CBS hit before the show's 200th episode, which airs in January, but regarding that particular milestone, executive producer Gary Glasberg says "there will be a lot of faces involved” in the event.

“We are planning a really unique and interesting episode of TV. I think it will be special for the people who have stuck with the show. We are putting a lot of time in it."
