Unfortunately, the ruling stands.

The only state that currently allows instant replay, is New Jersey. But it will only be used if the promoter provides the equipment, and makes the request for it to be used for a fight in advance.

I think because they have no such rule on their books, and because the ref did not see it at the time that it happened, they have to go with the refs decision, even though ESPN provided the proof. They can't reverse a decision, when their governering body has no rule as to the use of instant replay in their guidelines.

It's unfortunate though.
