The report claims the decision is "amicable and mutually agreed upon" between Grant and the CBS show's producers.
On Season 1 of NCIS: New Orleans, Grant's character (a former ATF agent recruited by the unit) was only a recurring role but in Seasons 2-4, Grant was promoted to a series regular. Her final appearance on the show will be Episode 17, which airs on April 3.
Steven Weber talks about the descent into villainy for his 'NCIS: New Orleans' character Mayor Hamilton.
"It's just time for a change," Grant's manager, Didi Rea, explained, "This is about moving on to the next great thing."
