Kurt Sutter temporarily sidelined from 'Sons of Anarchy' series finale

Update: Kurt Sutter is back in action Wednesday, and Instagrammed a photo to prove it.

Original post: As if there wasn’t going to be enough drama in front of the camera during the filming of Sons of Anarchy‘s final episode, there was some behind-the-scenes on Monday, when creator Kurt Sutter had to excuse himself from the director’s chair to have his appendix removed. Sutter, who also wrote the series finale set to air Dec. 9, tweeted a photo of his outed organ.

Fellow Sons EP Paris Barclay—who helmed the season premiere, as well as episodes 7, 10, and 12—has stepped in until Sutter returns, which his rep tells EW is still expected to be Wednesday.

In the meantime, Glen Mazzara, his former colleague on The Shield, is helping Sutter keep his sense of humor in tact.
