The McGregor card on Sunday before the superbowl was McGregor in Boston and nothing else. This is a Frank Mir and Obviously TRT deprived Bigfoot headlined card in Brazil, I don't think they expect much of this card imo. I've seen no ads for it, no real pretext or anything.
They seem to commit to a regular interval of Brazilian events and this is just to keep that up with the real focus being the Rousey card next week.
