When Glee returns in the fall, New Directions will be missing one voice – Chord Overstreet (who plays Sam Evans) will not be returning to the series (at least not on a full-time basis). TV Line reports that the actor;s contract has not been renewed. Last week, Overstreet tweeted: “It’s been a good year. Too bad it’s over. Time for summer and starting fresh.” In happier news, Darren Criss (Blaine) and Harry Shum Jr. (Mike) will return as series regulars next season.
