The UFC traveled to Brazil for the fourth time this year on Saturday with UFC Fight Night 51 from Nilson Nelson Gymnasium in Brasilia. In the main event,  Andrei Arlovski (23-10 MMA, 12-4 UFC) picked up his first knockout in UFC competition since March 2008 with a first-round stoppage of hometown hero  Antonio Silva (18-6-1 MMA, 2-3-1 UFC). “The Pit Bull” is now 2-0 inside the octagon since returning to the UFC in June. The win pushed Arlovski further up the list in several meaningful statistical categories, but he wasn’t the only one to accomplish a feat of note
