It had been rumored that Sudeikis was leaving the NBC sketch comedy show since the season finale in May, but the funnyman confirmed it during his appearance on the Late Show with David Letterman on Wednesday.
"I'm definitely done. I'm not coming back next fall," said Sudeikis, who has been with SNL for 10 years, two of which he worked as a writer, followed by eight years as on-camera talent.
