Tyler Breeze and Erick Rowan were seen arriving at the Dallas airport last night. Obviously, since Raw is in Dallas tonight, that means that both of them will be backstage during the show. We don't know if they will be appearing on camera.
Rowan has been out of action since June with an injury. Breeze, as first reported by Dave Meltzer, is scheduled to be brought up to the main roster. If he's not used on the show tonight then he's expected to be on Raw in the very near future.
