Heath Slater and Rhyno were forced to fight last week with WWE RAW in a match created by Baron Corbin that did not finish well for Rhyno. The match was for their work on RAW, which means that the loser will be fired and Slater won fast.
In a message to WWE.com, Rhyno denied rumors that he was hanging his boots. It turns out that Baron Corbin's abuse of power last week was not a sign that Manbesta's career is over.
"I did not retire, I had no plans to retire, obviously started after I competed in a match with Heath Slater and the loser was fired by Raw, which Heat Slater won – a match we had inaugurated by Baron Corbin."
This should answer your question about the future of Rhyno in the WWE. We are not entirely sure what he will do, but at least he does not retire to have more of it.
