Fred:

The event is not until July 7th (a Saturday). From my experience (and thanks to Chuck S. ) I have found that if they do release chips for this fight, they would probably not be released until the Friday before (July 6th).

You may be able to get a "heads up" if chips are going to be released by checking the Nevada Gaming Commission Chip & Token Report:

However, you will not see the July release report until early July. Good luck.
