They last shared the ring at Extreme Rules last year when Balor, portraying The Demon character, lost to Reigns when the top rope snapped as Balor was standing on the turnbuckle.
Near the end of an interview with WWE El Brunch, a fan asked Balor about facing Reigns again.
“Well, I think me and Roman Reigns have a lot of unfinished business. There was a little bit of a questionable finish to our last match at Extreme Rules when the top rope mysteriously broke in our championship match. I feel there’s a rematch due with myself and Roman. Hopefully, we’ll get to that soon after Clash at the Castle.”
