But B.J. Flores' opponent has changed, just five days before the opening bell.
David McNemar will come to the Shrine Mosque and take the place of Ahmed Samir.
Samir told the Flores camp that he broke his thumb training.

Flores is 27-1-1 and is the number one contendor for the WBO world cruiserweight title.
If he can win Saturday's fight, he should be in line for his long awaited title shot.
McNemar is 13-1 with ten knockouts.
Flores says the last second change in opponents is no big deal.
"I mean the fans are actually going to get a better fight," said NABO cruiserweight champ B.J. Flores. "I think I was knocking the Egyptian Prince out in four or five rounds. He never really been tested by a guy of my calibre. Now this guy has been tested a little more with a couple of decent guys. He's been 12 rounds a few times so he has more experience.
