When The Beast invades the east, he won't have his mouthpiece with him.

Seth Rollins Congratulates New TNA Champion EC3

According to Wrestlingheadlines.com, when Brock Lesnar enters the Beast in the East WWE Network special on Saturday, Paul Heyman won't be in attendance.

Heyman is not making the trip, so when Lesnar battles Kofi Kingston, he won't have his manager and spokesman by his side.

Lesnar is traveling with former AWA and WWE wrestler Brad Rheingans and the two are looking to visit retired wrestler Masa Saito, which is part of the reason Lesnar is going to Japan in the first place.

Heyman has been by Lesnar's side since his big comeback, but he won't be in Tokyo this weekend.

Lesnar is set to face Kingston, but despite the WWE Network special being billed as The Beast in the East, it's unlikely to be the main event.

It is expected that the former WWE World Heavyweight Champion will squash him in their match and though that bout and the NXT Championship clash between Kevin Owens and Finn Balor have both been given a lot of buildup, neither is expected to go on last.

Rather, the tag team match pitting United States Champion John Cena and Dolph Ziggler against King Barrett and Kane will be the main event.

After facing Kingston, Lesnar will go head-to-head with Seth Rollins for the WWE World Heavyweight Championship at Battleground on July 19 live from the Scottrade Center in St. Louis.

The Beast in the East airs live from Tokyo at 5:30 a.m. ET on Saturday.
