After getting a head's up from the Los Angeles Times, the Academy of Television Arts & Sciences noticed this week that Harris, 37, was inexplicably missing from the list of people collectively nominated for an Emmy for CBS's 2009 Tony Awards broadcast, which Harris hosted.
So, the Academy resolved the oversight, adding Harris's name to the existing nomination (alongside the show's producers) and bringing his Emmy nomination tally this year up to three.
He was previously nominated as best supporting comedy actor (for How I Met Your Mother) and best guest comedy actor (for Glee).
Harris, who also hosted the Emmys last year, earned high marks for his Tony hosting duties, although that show is best remembered for the moment when Bret Michaels was injured by a piece of moving scenery following his performance. This year's Emmy telecast, which airs Aug. 29 on NBC, will be helmed by Jimmy Fallon.
Fox's Glee leads the pack of 2010 Emmy nominees, with 19 nods.
