Glee Season 5: Say Farewell To...

When Glee Season 5 kicks off on September 19, four familiar faces will not be around to welcome viewers back to the Fox musical comedy. The network announced today (via TV Line) that the following actors/actresses will not return as series regulars:

Heather Morris (Brittany)
Mark Salling (Puck)
Amber Riley (Mercedes)
Harry Shum, Jr. (Mike)

In related news, Dianna Agron - who scarcely appeared as Quinn on Glee Season 4 - is not slated to make any appearances at all in 2013-2014. It is possible that any or all of the aforementioned quartet may pop up for at least one or two episodes, but it's too early to know for sure at the moment. Earlier this week, Fox announced its fall premiere calendar.
