From TVLine.com:
“His option to be a series regular was just not picked up at this time,” clarifies the source. “If Chord wants to appear on Glee, the choice is his. The Glee writers like his Sam character, and have plans to write for him. He and his reps have been told that he is welcome back to Glee, and everyone hopes he will show up on August 10 when filming begins.”
The insider points out that it took Shum “two years to become a regular,” adding, “If Chord has a great season, which we expect he will, then he will become a regular like Harry, possibly as early as January.”
