Roman Reigns and Cody Rhodes will compete for the WWE Undisputed Universal title in the main event of WrestleMania 40 night two, but it will be under Bloodline rules.

That was the stipulation that Reigns earned alongside his cousin, The Rock, by beating Rhodes and Seth Rollins on night one.

 That means anything goes, essentially. The Rock and The Bloodline will make the rules up as they go along, but that also means Rhodes might enlist some outside help of his own.

The hallmark of Reigns’ historic world title reign has been outside help from his Bloodline family during his matches and he’s unfairly defeated several stars along the way because of it.

There has been rumours stars like John Cena, Kevin Owens and Sami Zayn – men who have been wronged by Reigns – might appear to aid Rhodes, but Triple H has now alluded to maybe the greatest legend of them all.

Fans noticed that The Game tweeted at 15:16pm today – or 3:16. That is a number synonymous with Stone Cold Steve Austin.

Coincidence? Unlikely, especially given he appeared on a truck in the background of RAW when The Rock was beating down Cody Rhodes a couple of weeks ago.

Of course, Austin is a famous rival of The Rock and would be the perfect man to counter his influence on the main event.

Fightful had reported weeks ago that WWE had been in discussions with Austin about making an appearance in Philadelphia, but couldn’t confirm what those plans would be.

With WrestleMania 40 night two underway, we won’t have to wait long to find out what surprises the main event has in store.

Austin is generally regarded as the greatest box office attraction in the history of professional wrestling.

Ushering in the Attitude Era, Austin led WWE through their golden era both creatively and financially.

The Texas Rattlesnake was forced to retire in 2003 in his mid-to-late 30s due to ongoing health issues, many of which stemmed from a broken neck he suffered in 1997.
