As announced on WWE.com:
Brock Lesnar and Paul Heyman will be Chris Jericho's special guests on what might be the most volatile edition of "The Highlight Reel" to date. How will Y2J keep the peace, one week after The Anomaly assaulted WWE World Heavyweight Champion Roman Reigns?
This would seem to set up well for the annual "everyone rushes the ring to give us a preview of the Royal Rumble" segment that we get on the go home episode of Monday Night Raw heading into that pay-per-view, which is now just a week away.
Both Lesnar and Jericho are already scheduled for the Royal Rumble match. We'll no doubt get a few more names on our way to the second biggest WWE show of the year.
