The fight took place entirely on the feet, including at the end when Mein began pounding on Cyborg with elbows to the face. Although Cyborg didn't go down, he wasn't defending himself, and the referee made the right call to step in and stop the fight.
Mein said afterward that he considered it the biggest win of his professional MMA career.
"Very, very satisfying -- I'm happy that I finished the fight. That's what I'm going for every time and it came true," Mein said. "He was kicking me hard and my legs were sore so I stayed in the pocked and just kept picking away. I hit him with a nice body shot, that hurt him, and then the elbows to finish him."
Mein is only 21 years old and already has a 23-7 professional MMA record. He's already good and only going to get better.
Unfortunately, the 33-year-old Cyborg has now lost two in a row and four of his last six, and he's starting to show signs of aging. Cyborg has been through some tough battles in his MMA career, and Mein just put him through another one.
