In addition to Hogan and Bischoff not being at TNA’s latest Impact tapings, Jason Powell at Prowrestling.net says that creative team member Ed Ferrara was also not there. No confirmation yet, but he may no longer be with the company. (He had been part of creative meetings with Vince Russo, Matt Conway and Eric Bischoff.)
As for why Hogan & Bischoff weren’t there, Powell writes that Hogan is having back surgery later this week, and Bischoff wasn’t there due to being host of a Fourth of July event. Eric is also reportedly not scheduled for the next tapings, but you know how quickly things change in pro wrestling.
