The main event for the UFC's return to Brazil is set after the headliners made weight Friday in South America.

Ahead of UFC Fight Night 261 (ESPN+), which takes place Saturday at Farmasi Arena in Rio de Janeiro, former lightweight champion Charles Oliveira (35-11 MMA, 23-11 UFC) and short-notice replacement opponent Mateusz Gamrot (25-3 MMA, 8-3 UFC) stepped on the scale at the official weigh-ins.

Check out the video from their trips to the scale below.
