Charles Oliveira defeated Kevin Lee via third-round submission to close out UFC Fight Night 170 in Brasilia, Brazil, in front of a mostly empty arena.
The UFC opted to move forward with the event with "only staff that's running the event" amid concern over COVID-19 that has shut down most of the sports world.
The two submission specialists fought all over the cage in the first two rounds. Both traded submission attempts in the first round and striking exchanges in a mostly even round.
As it moved into the second round, Do Bronx started to take over.
