Kalisto got the ball rolling earlier Monday afternoon when he tweeted, "10 months... #freeagent". His Lucha House Party teammate Gran Metalik retweeted Kalisto, and added, "Me too carnal."
For more than a year, Kalisto and Metalik, along with Lince Dorado, have wrestled as Lucha House Party. Originally the trio were an act on 205 Live, before crossing over to Raw, wrestling teams with no regard of weight class.
Notable rivals for the group after moving full-time to Raw have included The Revival and Lars Sullivan.
Kalisto previously held the United States title twice, and briefly reigned as Cruiserweight champion in 2017. He's also a former NXT Tag Team champion with Sin Cara, known together as the Lucha Dragons.
Braun Strowman replied "Adios" to Kalisto's original tweet, one assumes playfully.
