UFC On ESPN+ 8 Results: Former Champion Stunned In Main Event

Former Strikeforce champion and top UFC contender Ronaldo "Jacare" Souza knew he was risking it all to headline Saturday night's UFC on ESPN+ 8 card. And Jack Hermansson took full-advantage.

Hermansson pushed his current win streak to four in a row with a decision victory over Souza in the main event from Sunrise, Florida live on ESPN+. The 30-year-old from Sweden replaced Yoel Romero in the bout.

Greg Hardy, a former NFL standout who has had several run-ins with the law, earned his first UFC win with a first round finish of Dmitrii Smoliakov in the co-main event. Hardy suffered a loss in his debut earlier this year after being disqualified due to an illegal strike.

Mike Perry, Glover Teixeira, Cory Sandhagen and Roosevelt Roberts were other main card winners, with Takashi Sato, Augusto Sakai, Carla Esparza, Gilbert Burns, Jim Miller, Angela Hill and Dhiego Lima all earning prelim victories.
