A lot has changed in the world of wrestling in the past decade.

For instance, staples of the attitude era included chair shots to the head and plenty of blood pouring as a result of foreign objects.

As the WWE has moved towards a PG rating with plenty more sponsors to appease, the blood has become virtually outlawed where possible and following Chris Benoit's murder/suicide and subsequent spotlight on concussions, chair shots to the head were also nixed.

So the WWE Universe was pretty shocked to see a 72-year-old Vince McMahon busted open by Kevin Owens on SmackDown Live two weeks ago courtesy of a visibly stiff headbutt.

What happened? Did McMahon use a blade? Did he cut himself beforehand like some reports suggested? Or did Owens cut him open the hard way?

Speaking on CBS Sports’ In This Corner podcast, the new face of the company Roman Reigns opened up on what really happened.

“I think it’s one of those situations where it’s a leading by example. When you see the CEO, your boss, out there getting shoot headbutted and thrown around at his age, it comes back to that word ‘passion’ that we talked about. You don’t have to. Let’s be honest, does he really have to be out there doing that stuff?

"And I’ve been in there and done some physicality with him, but never just a straight [headbutt]. You can watch that back. There is no sports entertainment in there. Do you know what I mean? There was nothing pulled. There’s no way to disguise that," Reigns asserted.

Reigns worked with McMahon at the tail end of 2015 in a bid to get a The Big Dog over with the fans against one of the most famous heels of all-time.

Despite everything he has seen, Reigns doesn't believe there is a possible way the headbutt wasn't real.

“Kevin, K.O.’s good, he’s a really good [pro] wrestler, but if he can somehow work that, I’ve got to sit him down and talk to him. I just think it kind of sets the tone and it makes everybody motivated because I’ve been out there with the boss. K.O. [has] been out there with the boss.

"People want to be out there with him, man. It says something. It elevates you and that’s what it’s all about, riding this escalator and generally growing, and progressing, and seeing your star rise. And sometimes, the boss has to come out there and help that situation.”
