"Glee's" Cory Monteith tribute episode will air in October, and according to E! News, several old cast members and guest stars will make appearances.
Titled "The Quarterback," Monteith's tribute episode will reportedly feature Amber Riley (Mercedes), Harry Shum Jr. (Mike Chang), Mark Salling (Puck), Jayma Mays (Emma) Dot-Marie Jones (Coach Bieste), Kurt's father Mike O'Malley (Burt Hummel) and Finn's mother Romy Rosemont (Carole Hudson-Hummel). Dianna Agron (Quinn) and Heather Morris (Brittany) will not be making appearances, according to E!
The episode -- which has been described as "gut-wrenching" -- went into production on Friday, and Lea Michele, Monteith's on and offscreen girlfriend, tweeted a photo of herself wearing a "Finn" necklace.
Additionally, Jane Lynch (Sue Sylvester) tweeted about the episode when she read the script last week.
Fox did not immediately respond to The Huffington Post's request for comment.
