“Cowboy” had a good start against “Gunni” in Toronto, Canada, on Saturday night, but Nelson was able to come back in the second round, take him down and get on the mount, from where he landed a vicious elbow that opened a deep cut in his forehead.
Nelson tapped the Brazilian with a rear-naked choke a few seconds later, scoring his first win since March 2017.
Oliveira returned to the losing column after a good run earlier this year, with stoppage victories over Carlo Pedersoli and Carlos Condit, but not even a deep cut made him stop smiling.
