“Pauley has been a valued member of both NCIS and the CBS family for over 15 years,” CBS said in a statement.

“While it’s never easy saying goodbye to a beloved actress and character, we respect her decision to leave at the end of the season. We are grateful to Pauley for all her contributions to the series and making Abby one of the most unique characters on television.”

“We’ve known for some time this would be Pauley’s final season on NCIS and have been working toward a special send-off,” NCIS executive producers George Schenck and Frank Cardea said in a joint statement.

“From day one, she has brought incredible passion and specificity to the role. Abby is a character that inspires millions of fans around the world, and all of us at NCIS are appreciative of Pauley for portraying her.”
