Petruzelli (14-8) made the announcement via his Facebook page on Friday. “I want to thank my family, friends, fiancé and fans for being by my side these past 13 years plus of my MMA career. Every time I fought it was to please and excite you but most of all make you proud of me. Up until a couple years ago it pleased and excited me as well.
