Ketlen Vieira defeated Miesha Tate by unanimous decision in their women's bantamweight bout Saturday night at UFC Fight Night in Las Vegas.
Vieira (12-2) took the cards 48-47, 48-47, 49-46.
"That's what I'm here for -- I'm here to fight the best," the Brazilian Vieira said via an interpreter afterward. "Respect my skills."
Tate, former bantamweight champion, was fighting in her second bout after a five-year layoff. She returned victorious in July with a TKO victory. But she ran into a problem in the fifth round as Vieira battered her en route to the win.
Tate (19-8) was taken to a local hospital for a CT scan on her head and face, UFC said afterward.
"I've always dreamed about being in a main event against a legend," Vieira said. "To be able to live that moment and get a victory, I don't have words to express."
In other action Saturday, Sean Brady outpointed Michael Chiesa, Taila Santos defeated Joanne Wood by submission (rear naked choke) in the first round, Rani Yahya won by unanimous decision over Kyung Ho Kang, and Adrian Yanez won by split decision over Davey Grant.
