Australian MMA veteran Anthony Perosh is retiring from active competition after more than 12 years as a professional fighter. “The Hippo” recently announced his decision on TeamPeroshMMA.com.au , the official website of Team Perosh Mixed Martial Arts. Perosh (15-10 MMA, 5-7 UFC) walks away after a pair of disappointing 2015 knockout losses to Gian Villante and Sean O’Connell but insists he leaves the octagon with his head held high.
