The Rock and Roman Reigns have entertained the idea of doing a possible match at WrestleMania 37.
Dave Meltzer reported in the latest edition of the Wrestling Observer Newsletter that The Rock wants to come in to put Reigns over in front of a big crowd.
However, due to The Rock being a movie star, studios have to protect their investments and insurance policies may prevent him from wrestling. This problem has been around since his second match with John Cena at WrestleMania 29, where he tore his abdominal and abductor tendons. That put the production of Hercules in question.
There have been ideas to bring him back to WWE over the years, but the problem mentioned above and his schedule has nixed those plans.
