His opponent, Oskar Piechota was a Middleweight champion in Cage Warriors and posed a legitimate test to the BJJ wizard's prospects of becoming a successful UFC fighter. However, not that big of a test by how it all panned out.
It took Vieira just under ten minutes to lock in the arm-triangle choke for a memorable win on his UFC debut.
Vieira landed a double-leg takedown in the first round itself and settled for the Butterfly guard. He controlled the fight on the mat owing to his big frame and won it dominantly.
Vieira continued the good work in the second round as he tried to set up another takedown and waited for his opportunity.
With only a minute to go in the second round, Vieira got into half guard position, got the mount, and efficiently caught Piechota in an arm-triangle choke. The tap came and so did the referee to stop the fight.
Result: Rodolfo Vieira def. Oskar Piechota via submission (arm-triangle choke) (4:26, Round 2)
A BJJ World Champion couldn't have asked for a better debut. Vieira showed what he's all about and extended his undefeated record to six professional MMA wins.
