RIO DE JANEIRO — Anderson Silva stopped Stephan Bonnar with a knee to the body with 20 seconds left in the first round Saturday night, winning his 17th consecutive fight in front of his home fans at UFC 153.
Silva (31-4) showed off his usual dominance while stopping Bonnar (17-8) for the first time in the veteran's career. Silva dared Bonnar to take a shot at him in the early minutes before hurting him with a knee and finishing him with punches on the ground.
Antonio Rodrigo Nogueira also defeated Dave Herman by armbar submission late in the second round at Rio's HSBC Arena, and UFC newcomer Glover Teixeira stopped Fabio Maldonado after two rounds for his 17th straight victory.
Silva has been the UFC's middleweight champion since October 2006, and he defended his title July 7 with a dominant victory in his rematch with Chael Sonnen. But when featherweight champion Jose Aldo and several other fighters dropped off the UFC 153 card because of injuries and schedule changes, Silva volunteered to headline the Rio show on just a few weeks' notice, even moving up 20 pounds to light heavyweight for the third time in his career.
Bonnar was among the biggest underdogs in UFC history, but gamely tried to engage with Silva before getting finished. Bonnar hadn't fought since last November, and unofficially considered himself retired.
