Could see that happening. Kind of similar to UFC 137 when Nick Diaz and GSP were scheduled for the main event for the WW title and Nick no showed a press conference so Dana made him fight BJ Penn at 137 instead and said if he won then he'd be the number one contender.
Only thing is, Overeem still could get fired/suspended by the UFC.
