WARNING: The following news item contains a MAJOR spoiler for season two of The Walking Dead.

In an ad hyping the release of this season's upcoming DVD, AMC appears to have accidentally revealed a significant plot point.

Aside from promoting features such as extended scenes and "Making Of" specials, and telling fans the 13-episode set can be pre-ordered now for an August shipping, the network spoiled the fate of a major character.

AMC eventually removed the post from its online store, saying in a statement that it was "completely unauthorized" and "the matter is currently under investigation," but we've published a screen capture in our photo gallery.

View it HERE and read the description of the DVD if you wish to be spoiled.
