It wasn’t long ago when NBC decided to air a special episode of America’s favorite comedy sitcom, “Friends.” While the reunion is still on, there is one slight twist to the plot.

Matthew Perry, who played Chandler Bing, won’t be able make the special tribute alongside his “Friends” co-stars: Courtney Cox (Monica), Jennifer Aniston (Rachel), Lisa Kudrow (Phoebe), David Schwimmer (Ross) and Matt Leblanc (Joey), a USA today report has confirmed.

Perry will be concentrating on his play, “The End of Longing,” which is a dark comedy he has written and will star in. He confirmed his absence for the tribute while speaking on the “The Graham Norton Show.” The rest of the cast will be present for the event and Perry said that he “may tape something for the tribute.”

The special episode is a tribute to the career of television director James Burrows, who directed 15 episodes of “Friends” including its pilot. James is widely considered as one of the most important directors since the 70s.

David Schwimmer has expressed his disappointment over Perry’s decision, stating that he was “sad” but at the same time “happy” that his co-star is doing a play in London.

“I wish I could say it was going to be a reunion. Anyway, (It’s a) 5/6 reunion,” Schwimmer was quoted in IBN Live.

“Sure I’m sad, but I’m happy for him, he’s doing a play in London and it’s thrilling. I did one there and it was fantastic” he added.

NBC’s network entertainment chief Bob Greenblatt had earlier confirmed the special episode, but he was not sure if all six actors could make it.

“I shouldn’t go into detail. I’m hoping that all six of them will be there in the same room at the same time. I don’t know, logistically, if we can pull that off,” Greenblatt stated.

The special is scheduled to air on February 21 at 9 pm on NBC.
