Updated July 5, 2011, 2 p.m., to clarify that Chord Overstreet was not considered a regular during the past season of "Glee."

‘Glee’ is making some cast changes, including cutting one of its main cast members, reports Deadline.com. Meanwhile, two other cast members are being upgraded to series regulars.

Chord Overstreet, who plays transfer student Sam Evans, will not be back on the Fox show, according to the story. Overstreet appeared on most of the episodes during the past season, but technically was never considered a series regular, but rather a guest star.

Late Friday, Overstreet issued a cryptic tweet that read, “It’s been a good year. Too bad it’s over. Time for summer and starting fresh," the story notes.

It’s possible that Overstreet could return occasionally as a guest star, the article notes.

Darren Criss, who plays Blaine, and Harry Shum Jr., who plays Mike, have been bumped up to full-time regulars starting with the show’s third season this fall, the story notes.

Ashley Fink, known for her role as Lauren Zizes, will remain a guest star and her role may be scaled back, the piece notes.
