As a result, Ava and Santino came up with a joint show called Showdown, where stars from both brands squared off in Survivor Series-style matches. However, it looks like this didn't settle the feud between the companies. This week on TNA Impact, Mike Santana defended his TNA World Title against Ryan Nemeth. During the match, Nic Nemeth's music played, and he was shown walking backstage. However, he was suddenly attacked by a hooded figure. Following this, several NXT stars such as Brooks Jensen, Lexis King, Stacks, Robert Stone, and Charlie Dempsey stormed the ring and ambushed Mike Santana. Several TNA stars like Steve Maclin and The Rascalz tried to intervene, but the numbers were in NXT's favor.Following this invasion, NXT GM Ava took to social media to wash her hands of the matter, stating she had nothing to do with what happened on Impact. Shawn Michaels responded to her that he would look into the incident."I’m looking into it. #TurningPoint," wrote Michaels.Check out his tweet here:Vince Russo believes Shawn Michaels had a hand to play in Candice LeRae getting a new backstage roleA few weeks ago, it was reported that Candice LeRae secured a new backstage role as a producer.
