Taz quit TNA Wrestling, Wrestling News World can confirm.
While issues regarding pay were the main reason, there was another element as well. Taz hated working with Josh Mathews and wanted his former broadcast partner Mike Tenay brought back to Impact. Josh is "Big" John Gaburick's guy and isn't going anywhere, however, that became a major issue.
Many in the company believe that Taz would have been a little more patient with the checks had he still been working with Tenay.
It's true TNA tried out Al Snow in Taz's position. When Taz found out and confronted Mathews about it, Mathews denied he'd been working with Snow, even though Taz knew the sessions had taken place.
