Yes and no. As a business, it's the UFC's job to look beyond current fights, and I'm sure the idea of Reem vs. Cain and Evans vs. Silva was very appealing to the top brass. On the other hand, guys like Dana White are also fans and jump out of their seats for those 'Holy s-hit!' moments the same as you and I. It certainly makes future bookings more difficult, but I doubt anyone is actually peeved.
With Evans it's another story. I'd imagine Dana might be annoyed, but that likely has more to do with just how poor the fight was.
