The massive Silva weighed in at 264 pounds for the scrap, and the former UFC champ Arlovski came in at 248. The two engaged in an intense, but incident free stare down right after.
The fight will mark the second time Arlovski and Silva have fought, as the latter defeated the “Pitbull” by unanimous decision at Strikeforce’s “Heavy Artillery” card in 2010.
All of the other competitors made weight for Saturday’s card, which will go down at the Nilson Nelson Gymnasium in Brasilia, Brazil.
