Jairzinho was coming off of the first loss of his MMA career, a 20-second knockout at the hands of future heavyweight champ Francis Ngannou. In dos Santos, he faced an opponent also in need of a win after being finished in his past two fights.
After a mostly uneventful opening round, Rozenstruik found his range late in the second and he proceeded to unleash a swarm of heavy punches on dos Santos. The Brazilian legend defended as best he could, but eventually succumbed to strikes for a third straight bout.
Rozenstruik failed to build off of this win, dropping a unanimous decision to Ciryl Gane in his next outing, but he has another chance to stay relevant in the rankings when he fights Augusto Sakai next Saturday in the main event of UFC Vegas 28.
