LAS VEGAS — Ronda Rousey's armbar streak is over. Her attention is now on the opponent's liver.
Rousey successfully defended her Ultimate Fighting Championship women's bantamweight title Saturday night at Mandalay Bay, delivering a left knee to challenger Sara McMann's stomach area, a notoriously painful liver shot that ended the bout by technical knockout 1 minute, 6 seconds into the first round.
After the fight opened with an exchange of punches, Rousey pressed McMann to the cage and originally landed a right knee toward the belly before switching legs on the attack.
The Rousey left knee dug in, McMann crumpled to the canvas, clutched at her body and couldn't rise, as referee Herb Dean leaned in and stopped potential Rousey punishment.
The stoppage seemed premature, and the crowd booed Rousey.
In the co-main event, Daniel Cormier not only wanted to quickly make a name for himself upon arrival in the UFC light-heavyweight division, he wanted to close the trap of opponent Patrick Cummins.
Cormier needed just 79 seconds to knock out his former training partner from Dana Point, Calif.
