The Wells Fargo Center holds the latest installment of MMA action when UFC 133 takes place in Philadelphia, Pennsylvania this Saturday night. Opening the main card off, Rory MacDonald (11-1) is set to prove how dangerous he is when he faces submission artist “Quicksand” Mike Pyle (21-6-1). “El Conquistador” Jorge Rivera (18-8) was originally slated to trade hands with “Legionarius” Alessio Sakara (15-8) but will now face Constantinos Philippou (7-2) after the latter suffered an unfortunate ACL injury. Two of the sport’s most seasoned veterans grace the card when “Superman” Dennis Hallman (45-13-2) and “Bad Boy” Brian Ebersole (40-14-1) meet. In the co-main event, “The Phenom” Vitor Belfort (19-9) will test his lightning fast hands against the always game Judoka, “Sexyama” Yoshihiro Akiyama (14-4). The night ends with a bang when “The Huntington Beach Bad Boy” Tito Ortiz (16-8-1) steps in on short notice to replace “Mr. Wonderful” Phil Davis (8-0) against “Sugar” Rashad Evans (15-1-1) in the main event. Evans stood in line for the next shot at the 205lbs. belt until injuries set him back, and Ortiz appears to have a second wind in his career. In such a pivotal time for the light heavyweight division, this encore of their 2007 battle could spell out serious title implications for the victor.
