The crowd booed the stoppage when it occurred 66-seconds into the fight. When the replay was shown on the screens inside the Mandalay Bay Events Center the booing increased exponentially.
Dean stepped in at the 1:06 mark and waved off the fight after McMann crumpled to the mat after Rousey delivered a knee to the body of her opponent. McMann was down on her knees and had one hand planted on the mat after the knee landed, the other arm was holding her midsection - clearly in pain. It did appear that McMann was attempting to get back to her feet, but by that time Dean had stepped in and called the fight in favor of Rousey.
McMann did not argue the stoppage.
UFC president Dana White gives his opinion on referee Herb Dean's work during UFC 170's main eventUFC president Dana White spoke about the stoppage at the post-fight press conference, saying, "You get hit to the body like that, and regular people who have never been hit to the body have no f------ clue what that feels like. Believe me when I tell you. She went down on her knees and she turned her head the other way. Could Herb have let her take some shots to the face? When the fight happened when I saw it, I said ‘oh man.' then I watched the replay and I thought it was a good stoppage."
The win moved Rousey's record to 9-0. All of those fights have ended by stoppage (8 submissions, 1 TKO), and only one has gone past the first round. McMann's record falls to 7-1 with the loss.
