Johnny Walker took home a $50,000 Performance of the Night bonus from UFC Argentina on Saturday night.
The 25-year-old Brazilian was making his octagon debut in a light heavyweight bout against Khalil Rountree.
It took Walker under minute to make an impression on the promotion. After landing a head kick, Walker stunned Rountree with two brutal elbows.
The second of those had his opponent on the deck and the fight was over following the intervention of the referee shortly after.
Johnny Walker so massive with that 6'6" frame. The patience with which he controlled that Thai clinch was nasty. Seven straight wins — another intriguing young prospect for 205. #UFCArgentina
