Former UFC lightweight champion Charles Oliveira takes on Polish standout Mateusz Gamrot in the main event of UFC Rio this Saturday. Veteran Gamrot, who has won four of his last five bouts, stepped in on short notice to replace Rafael Fiziev, who withdrew due to a knee injury. Oliveira has won his last six fights in his country Brazil. He is a slight favorite ahead of what is shaping up to be a blockbuster end to the night's action in the Octagon.

Charles Oliveira vs. Mateusz Gamrot Fight Preview
Charles Oliveira: form and statistics
"Do Bronx" is the former lightweight champion, and the question remains if the submission specialist has the zeal to mount another title run following a loss to Ilia Topuria in his latest bid. Before that, Charles Oliveira will have to adjust to Mateusz Gamrot, a grappler, after initially training to fight Rafael Fiziev, a striker. At 35, the veteran Oliveira is a celebrated fighter, holding the record for most submissions in the UFC and most finishes. The No. 4-ranked lightweight lost to Topuria by a KO last June at UFC 317 in another failed bid for the vacant UFC lightweight title. Oliveira has two wins from his last five.
