During their 50th anniversary celebration of the 1969 World Series champs on Saturday, the Mets honored members of that team who have passed away with an in memoriam video. But not everyone in the video is dead.

The tribute bizarrely included two ’69 Mets who are still alive — Jim Gosger and Jesse Hudson.

Someone from the Mets phoned Gosger after Saturday’s game to apologize for the error, and a source told The Post’s Zach Braziller that Gosger took the flub in stride. The Mets were hoping to get in touch with Hudson to apologize as well.

Gosger, 76, played in 10 regular-season games as an outfielder for the Mets in 1969 and returned to the club in 1973 for a two-season stint. Hudson, 70, made one relief appearance for the ’69 Mets, his only big-league game.
