I had a quick look at his career cross-referencing the matches listed on Cagematch with his general Wikipedia profile and I can't find any evidence which suggests that he was in TNA at any point. He has wrestled sporadically in the WWE as Jon Moxley (as enhancement talent) in the past jobbing to the likes of Val Venis from 2006 until he was eventually signed in 2011 so it's possible that you may have seen one of these matches at some point. Apart from that, CZW and Dragon Gate USA are the promotions I'd associate him with most prior to his WWE run.
that youtube link ya posted is brilliant
Glad you liked it. Here's another featuring Moxley at his psychotic best.
