Heather Morris, Mark Salling, Harry Shum Jr. and Amber Riley are no longer series regulars on the FOX musical series, joining Dianna Agron.
Another graduation means more familiar characters leave McKinley High on "Glee". TVLine has learned that at least four original cast members won't return as series regulars in the upcoming season 5.
They are Heather Morris (Brittany), Mark Salling (Puck), Amber Riley (Mercedes) and Harry Shum Jr. (Mike). The foursome joins Dianna Agron, whose appearance has been reduced to only a handful of episodes in season 4. They all, however, may still return as occasional guest stars.
Salling, Riley, Agron and Shum Jr.'s characters were among those who graduated from McKinley High at the end of season 3, but the show's writers still found ways to insert them in season 4's storylines. Meanwhile, Morris' Brittany has been accepted to MIT last season. The actress' pregnancy has been reported as a reason why she won't be available to join the months-long production for next season.
