I believe Quarry fights at 185 as opposed to Griffin at 205, so they wouldn't be matched up unless one of them changes their weight class for the fight. It could happen, but I don't know why either of them would move up or down for the time being.
Here's the scoop. Spike filmed this documentary as part of the buildup for the fight. Tito wanted to cash in on the fight and had Jenna Jameson (his girlfriend/business manager) go to UFC and demand more money.
