TNA reportedly reached out to Lucha Underground for a joint show during WrestleMania weekend. Lucha Underground didn’t want to do it with the feeling being that it would be a bad mix.
Also, WWE and Lucha Underground officials met in December.
There were discussions involving talent, but those talks went nowhere. Vince McMahon was not at the meeting, but key people like Paul Levesque and Canyon Ceman were there.
