Brock Lesnar not removed from advertising WWE Royal Rumble go-home episode
As noted, Hulk Hogan, Kevin Nash, Scott Hall and Shawn Michaels are advertised for the WWE Royal Rumble go-home episode of Raw on January 19, 2015 at the American Airlines Center in Dallas, Texas.
Regarding reports of Brock Lesnar being removed from advertising for the show, that is not the case.
The official website of the American Airlines Center still has Lesnar listed for the event, although he appears farther down on the page.
WWE's website also updated their page for the event and Lesnar remains on the listing.
Here is a video of Brock Lesnar interfering the match between Chris Jericho vs Paul Heyman:
