I think both Carlos and Barao should have been forced to defend their make believe belt from the get go. I can understand if the champ is 3-4 months from returning. However, if the champ just had ACL surgery (like both of these situations), you need to get out there and fight.
The point of the interm belt is to keep the division moving. It can't move with both the champ and the pretend champ on the sidelines.
Glad to see this match booked now though.
