-- Cena is scheduled for Raw shows at the end of January and beginning of February, but otherwise appears to be booked for pretty much all of the PPVs on both brands until WrestleMania by virtue of his "free agent" status.
-- Apollo Crews appears to be the replacement for Enzo Amore for the WWE Mixed Match Challenge to air exclusively on Facebook beginning January 16. WWE subtly introduced Crews to its advertising without much of an announcement.
