Today's WWE news and updates are headlined by Roman Reigns and The Undertaker. The two superstars are set to face each other at WrestleMania 33. The other news features Shinsuke Nakamura's main roster debut, Japanese star signing with the WWE and more.

Roman Reigns to beat The Undertaker at WrestleMania 33

According to Cageside Seats, Roman Reigns is currently penciled in to defeat The Undertaker at WrestleMania 33. The result could still change depending on Vince McMahon and the final outcome will surely get changed over and over until April 2.

The WWE is also not planning to turn Roman Reigns heel against The Undertaker but they should expect more boos for "The Big Dog." If he indeed beats "The Deadman" at WrestleMania 33, he is going to get a lot of heat from the fans and the WWE should use it to turn him into a bad guy.

Shinsuke Nakamura to get called up later this year

Many fans are waiting for the main roster debut of two-time NXT champion Shinsuke Nakamura. However, they have to wait until later this year for it to happen as he is not scheduled to get called up after WrestleMania 33, per Sportskeeda.

"The King of Strong Style" has nothing more to do in NXT and he should be on the main roster already. He was linked to a match with A.J. Styles for WrestleMania 33 but Shane McMahon has already started his feud with "The Phenomenal One."

WWE signs Japanese star Kairi Hojo

According to Dave Meltzer of The Wrestling Observer Newsletter, the WWE have signed STARDOM star Kairi Hojo to a three-year deal. She is expected to make her debut in NXT after WrestleMania 33. She joins fellow Japanese stars Asuka, Hideo Itami and Shinsuke Nakamura on the WWE roster.
