Jason Sudeikis has confirmed leaving Saturday Night Live during his Wednesday appearance on CBS’ Late Show With David Letterman.

“I’m definitely done. I’m not coming back next fall,” Sudeikis told Letterman.

Sudeikis, an SNL regular, has contributed to the show for 10 seasons. Having a checklist of things to do before leaving, Sudeikis fulfilled an objective by mentoring incoming writers for he was one of them for his first two seasons at the show.

Sudeikis’ farewell from NBC’s sketch comedy series comes weeks after Fred Armisen annouced he would not be returning to the show and two months after Bill Hader parted in the May 18 season finale.

“You never really leave that place, and it never leaves you. It’s an emotional journey getting through a season, much less the final one,” Sudeikis said to Modern Luxury magazine last year, the first sign of Sudeikis’ departure from SNL.

With a busy feature film schedule, Sudeikis is starring in “We’re the Millers” (out Aug. 7) and is working on a “Horrible Bosses” sequel, “Tumbledown” and “Relanxious”.
