“NCIS” is saying goodbye to another agent, but she might not get the same emotional exit that Tony DiNozzo received. Tess Monroe, who joined Gibbs’ team last season, will not return in Season 14.

Actress Sarah Clarke started appearing as Monroe in the last few episodes of Season 13. She was going to be one of the agents filling the void left by DiNozzo (Michael Weatherly), and the actress’ contract had an option to become a series regular. It seems the CBS drama decided not to pick up that option. TVLine reports that Clarke will not appear in Season 14 at all.

Monroe was introduced in the final two episodes of “NCIS” Season 13 as a strong agent who transferred from New York to D.C. It isn’t clear how her sudden absence will be explained.

Monroe joined the team around the same time former MI-6 Officer Clayton Reeves (Duane Henry) did, but they have very different futures. Unlike Clarke, TVLine reports Henry has been upgraded to a series regular.

NCIS doesn’t seem to be short-staffed, though. Jennifer Esposito will join the team as Special Agent Alexandra “Alex” Quinn. Gibbs (Mark Harmon) will convince her to reenter the field after spending some time working at the Law Enforcement Training Center. Gibbs knows she has “sharp wit, quick mind and immense talent as a federal agent,” according to a press release.

Wilmer Valderrama is becoming a series regular as well. The former “That ‘70s Show” star will play an agent who has been deep undercover for years. He has finally resurfaced and returns to the office to work with Gibbs, who might have trouble with the fact that he is an “an unpredictable, charismatic loose cannon.”

“NCIS” Season 14 premieres Tuesday, Sept. 20 at 8 p.m. EDT.
