But it was a controversial TKO, as referee Dan Miragliotta pulled Hendricks of Sadollah even though Sadollah appeared to be intelligently defending himself.
Hendricks landed several solid left hands that knocked Sadollah down, but at no point was Sadollah unconscious, and he appeared to be defending himself and aware of his surroundings.
As the fans in Philadelphia booed the stoppage, Hendricks tried to explain to them that they shouldn't be booing him.
"I'm in here to do one thing: Fight until the ref pulls me off," Hendricks said. "I didn't stop it."
It was Miragliotta who stopped it, and he deserves the scrutiny he'll get. But Hendricks also deserves plenty of credit for improving his MMA record to 6-0.
