There is no word on what happened to Parisyan, other than the UFC referring to it as a "last-minute back injury." Parisyan-Yoshida was scheduled for the televised portion of the card.
A match-up with Yoshida would have been a good one, and if Parisyan's injury isn't too serious, it would make sense for the two to fight again at a later event, perhaps UFC 89 on October 18.
