It sounds like someone is about to step inside the Hell in a Cell cage with The Fiend! An advertisement for the upcoming Hell in a Cell PPV claims that Bray Wyatt will end up challenging either Seth Rollins or Braun Strowman for the Universal Championship depending on which of them wins at Clash of Champions.
The card is, of course, subject to change but putting The Fiend in a setting like this and having him defeat either Rollins or Strowman for the Universal title makes perfect sense.
After all, it feels like the next natural step for The Fiend after his recent displays of dominance and he would make for a incredible Universal Champion. We'll just have to wait and see how things pan out but don't be surprised if plans start becoming clearer as soon as Clash of Champions!
