One thing I was thinking about home field advantage (or disadvantage), aside from the excess pressure it puts on to perform, is that fighters are not likely to pull out with an injury in their hometown. They will fight though the injury just to be on the card. Nog rushed his rehab back from the surgery to get on the card. Anderson has been known to fight with injuries in the past (ie Lutter, Sonnen). He definitely wouldn't pull out of this fight no matter what happened.
