MMA Junkie has confirmed with UFC officials that Alves will no longer compete on Saturday. The reasons for his withdrawal, however, are not known yet.
The UFC is reportedly looking for a replacement opponent for Perry.
Alves is coming off a decision win over Patrick Cote in April, which was just his second fight since 2015. Perry, meanwhile, knocked out Jake Ellenberger in his last fight, which also went down in April.
UFC Fight Night 116 will be headlined by a fight between former middleweight champ Luke Rockhold, and former WSOF champ, David Branch.
