For those who missed it, Chris Jericho hosted a returning segment of the "Highlight Reel" on Raw tonight, and after his usual non-speaking antics for the better part of the segment, he simply said, "this Sunday, at the Royal Rumble, it will be the end of the world as you know it." He then exited to the back.
It was announced by Cole and Lawler before the segment that Jericho will be a participant in the Royal Rumble match on Sunday night.
