Will Roman Reigns and Brock Lesnar brawl before WrestleMania?

In this no-holds-barred interview, the WWE World Heavyweight Champion gets brutally honest about The Big Dog, Roman Reigns.

One week after Roman Reigns momentarily silenced Brock Lesnar’s verbose advocate, Paul Heyman, The Big Dog will find himself within mauling distance of the ravenous WWE World Heavyweight Champion. Just six days before locking horns at WrestleMania, will the face-to-face confrontation between Reigns and The Beast Incarnate end in brutality? If so, for whom?  

How will Triple H respond to Sting?

See what The Vigilante had to say after Raw went off the air in this exclusive interview: Courtesy of the award-winning WWE Network.

Last Monday night, as Seth Rollins attempted to orchestrate a plot to ensnare Randy Orton, Sting mysteriously appeared to help The Viper lay waste to Mr. Money in the Bank and his Authority associates. Sting’s surprise team-up with WWE’s Apex Predator sent a powerful message of defiance to his WrestleMania opponent, Triple H, who was visibly shaken by the sudden emergence of the baseball bat–toting enigma.

Sting would go on to address the WWE Universe after Raw went off the air, exclusively on WWE Network, reiterating that he’s ready to take The Game down on The Grandest Stage of Them All. How will Triple H address his face-painted foe this Monday night?

Does retribution await Bad News Barrett?

Fed up with the game of “hot potato” several Superstars have been playing with the Intercontinental Championship in recent weeks, Bad News Barrett laid out at both Dolph Ziggler and Daniel Bryan on SmackDown, holding his reclaimed title high above two of his battered WrestleMania opponents.

Even though the night ended less than favorably for Ziggler and Bryan after their incredible efforts in the night’s Intercontinental Contenders Gauntlet Match, The “Yes!” Man and The Showoff never stay down for long. Will one — or both — of these Superstars get some payback against the Intercontinental Champion on Raw?

Will Randy Orton get his hands on Seth Rollins?

Randy Orton’s not the most patient Superstar on the roster, and we seriously doubt he’s going to wait until WrestleMania to get ahold of Seth Rollins again. Although several other members of The Authority suffered The Viper’s wrath Thursday night on SmackDown, Mr. Money in the Bank evaded an RKO. However, as history has taught us, WWE’s Apex Predator doesn’t let his prey run for long. Will The Viper sink his fangs into “The Future of WWE” on Raw?

Is Rusev afraid of John Cena?

John Cena and Rusev make their Show of Shows battle official, live on Raw.

United States Champion Rusev is many things: cunning, powerful, intimidating and, most importantly, unbeaten. But is he also getting nervous? Last Monday on Raw, in the final moments of a bizarre contract signing with his WrestleMania opponent John Cena, The Super Athlete flipped a table onto the Cenation leader and made a quick escape up the ramp. If Rusev is truly as unstoppable as he claims to be, why didn’t he stand and fight? Does he know that his U.S. Title reign is nearing its end? Is the reality that he’s about to suffer his first defeat — on The Grandest Stage of Them All, no less — beginning to sink in? Or is Rusev simply toying with Cena before crushing him at The Show of Shows? Expect some serious fireworks between Cena and Rusev before their anticipated WrestleMania rematch.

Tune in to Raw at 8/7 C on USA Network, and don’t miss Raw Pre-Show at 7:30 ET, only on WWE Network.
