Former WWE and TNA star Shawn Daivari worked the last set of Lucha Underground tapings, and he noted on Instagram he has indeed signed a deal with the company:

Daivari had said this via Instagram:
“Now that the cats outta the bag I feel like I can talk to u guys again. I signed a contract with [HASHTAG]#luchaunderground[/HASHTAG] and am officially back on TV. LU is the best thing going today for one reason; instead of being a copy of a copy of a copy they threw out the entire f–king play book and said ‘let’s start with what’s hot in 2015. What a f–king idea, RIGHT?!?! Shoulder handled thanks to @spidertechtape”
I vaguely remember him in the WWE, I didn't really watch much for a couple of those years.. I remember him a lot though from his little over a year in TNA as 'Sheik Abdul Bashir'..
IMO not a bad signing for LU, I remember hearing he's a pretty solid worker and if people recognize him it definitely brings a little bit more publicity to the company I suppose.
