Dianna Agron, Heather Morris and a couple of other actors will not be returning to Glee season 5 as series regulars.

The news comes today from TVline.com who has learned exclusively that Amber Riley (Mercedes), Heather Morris (Brittany), Mark Salling (Puck), Dianna Agron (Quinn) and Harry Shum Jr. (Mike Chang) will not be returning to Glee season 5 as series regulars. TVLine is reporting that though they will not return as series regulars, all five of the actors except for Amber Riley may return to the series as a guest star if needed for an episode.

Many fans of the show wondered how Glee would continue to include the graduated seniors in to another season of the show. The five stars who will not be returning had very small, uninteresting roles during season 4.

At the end of season 4 we also learned that Brittany Pearce was accepted in to MIT, with the finale feeling like a true send off of both the character and the actress. Fans who follow Heather Morris were also speculative of Morris’ return in Glee season 5 when it was revealed that she was pregnant and due in October (months after Glee will have returned to filming).

One of the main complaints of what was otherwise a fantastic season 4 was the overflowing cast of characters as Glee struggled to balance the older characters with the new recruits at McKinley High School.

There have been next-to-no details regarding the direction we will see Glee season 5 take when it returns Thursdays starting in September.

This news is somewhat bittersweet for fans of the show who have watched the development of several of these characters since its inception in season 1 back in 2009.

Details about Glee season 5 will continue as production inches closer to returning in the coming months. We’ll be sure to keep you up to date with the latest information and news surrounding casting.
