According to PWInsider, Eric Bischoff was absent from tonight's Impact Wrestling taping, and he may not be coming back in the near future, according to a few of their sources. Bischoff is the Executive Producer in charge of creative, which means his presence at TNA events should be more noticeable than most. He came to the company alongside Hulk Hogan in 2010.
Speaking of Hogan, TNA has been making it a point not to mention his name on any of their broadcasts, including tonight's Impact Wrestling and last weekend's Bound for Glory pay-per-view. Dixie Carter made reference to Hogan, but not by name, saying "who will remain nameless." TNA even asked a fan dressed up in full Hogan gear at Bound for Glory, George Antoun, to remove his costume and replace it with a TNA-themed shirt instead. This was after they took his Hulk Hogan sign away before the show.
With Bischoff missing from TNA events, and the company being so adamant against Hogan being anywhere near the product, this has led to a lot of speculation that, as the duo came to TNA together, they may be leaving together as well. Of course, this is all speculation so far, and we will update the story as more information becomes available.
