Ricochet, known as Prince Puma in Lucha Underground, is reportedly not taking any more bookings after June. The Wrestling Observer Newsletter reports that it's very likely he's headed to WWE in the near future.
WWE had previously shown interest in him, but he was under contract to Lucha Underground. His contract finishes after filming the third season of Lucha Underground next month, but he isn't supposed to work for competition for another 6 months after the season finishes airing in late 2017. The Observer reports that it would be hard for LU to enforce that as they don't pay him during that time, as opposed to WWE's 90-day no compete clause where talent does get paid during that time.
Additionally, New Japan is currently looking for a replacement for Ricochet. He currently works for New Japan as Matt Sydal's partner.
