Big Show was noticeably missing from Monday Night Raw this week. WWE has given him some time off to heal from the hand injury that he suffered at a live event over the weekend. Management had Brock Lesnar attacking him during Royal Rumble 2014 to write him off of television.
The widely held belief is that Brock Lesnar would be immediately booked into a rematch against Alistair Overeem if he decides to return to UFC. Overeem was the person that defeated him for the heavyweight championship before he decided to retire from MMA and return to WWE.
In a move that might have been encouraged by Dana White to promote the potential return, Alistair Overeem called out Brock Lesnar after defeating Frank Mir at a UFC event this past weekend. Lesnar is attempting to work with WWE on making his MMA return possible.
