A 31-year-old MMA fighter called Bruno Silva won by first-round knockout Saturday at a UFC event in Las Vegas.

It was also Silva's first fight in three years, but he showed no signs of ring rust to advance his pro MMA record to 20 wins (17 knockouts and three decisions) against six losses.

"I was already champion," Silva said, according to MMA Fighting. "This is my 17th knockout. I came here to be champion, too. I come here to do or die. I'm a striker. I try to end the fight wherever it is."
