LAS VEGAS – Anderson Silva’s final UFC appearance is officially on for Saturday, as both he and rival Urea Hall weighed in during Friday’s official weight-in.

Silva (34-10) scored 184 pounds for his middleweight men’s event against Hall (15-9).

The 45-year-old Silva will be his final as Saturday’s bout, but he has admitted that he is likely to be the last time he will fight. UFC President Dana White has promoted Silva as the last trip to the Octagon.

Silva is considered one of the greatest fighters in mixed martial arts history. He made his UFC debut in 2006 and won his first 16 fights. He held the 185-pound title from 2006 to 2013 and was widely regarded as the world’s best pound-for-pound fighter during that stretch.

The UFC actually booked this fight against Hall – weighing 184 pounds – in Brazil the year before, but Silva was forced to withdraw due to health issues. Hall has won three of their last four bouts. His only loss came recently for 2018 challenger Paulo Costa.

Saturday’s UFC event lost a bantamweight bout between Priscilla Cachioira and Kourtney Casey. The UFC announced on Friday that the 135-pound fight was canceled after Kachoeira was left with a card due to “weight management issues”. Neither Kachoeira nor Casey weighed in on Friday.

Former NFL player Greg Hardy’s heavy fight against Maurice Green is official. Hardy initially weighed 266.5 pounds and was given 265 pounds an hour to bite. He was reduced to 264.5 pounds.
