AMC said the panel that was scheduled for Saturday afternoon is on the same day as the funeral services for John Bernecker, the stuntman who died July 12 after plunging headfirst from a balcony on the show's Georgia set.
Production on season eight was briefly shut down, and multiple investigations are underway, according to The Hollywood Reporter.
"We wanted to make you aware that, unfortunately, we will no longer be able to present our panel with The Walking Dead executive producers. The panel conflicts with the funeral services for our stuntman John Bernecker, which Scott Gimple and some of the other EPs will be attending," the network announced.
The decision to cancel the TCA appearance comes after "The Walking Dead" cancelled all Comic-Con appearances except for the show's panel and autograph signing last weekend.
The panel for The Walking Dead opened with a heartfelt tribute to Bernecker.
