Seconds later, the match was over. But not in the manner Bader probably anticipated.
As Bader flung wild punches, Teixeira drilled Bader with a counter right and immediately followed with a crushing left hook to the chin. Bader crumpled to the mat, then Teixeira followed up with a dozen shots on the ground before referee Herb Dean stopped the fight.
The Brazilian native, who trains with John Hackleman at The Pit, earned his 20th consecutive victory at 2:55 of the first round.
"He was able to give me a punch that hurt me and knocked me down, but I saw everything that was happening and I knew exactly what was happening," Teixeira said through an interpreter.
It was said before that fight that with an impressive victory on Wednesday, Teixeira, who is now 5-0 in the UFC, would get the winner of Jon Jones vs. Alexander Gustafsson. Teixeira voiced confidence in his title hopes, but said he can do better.
"To tell you the truth, I wasn't happy with this fight," Teixeira said. "I was disappointed he was able to knock me to the ground. ... I'm telling you, this belt is going to be mine. I don't care if it's Jon Jones or if it's Gustafsson, it's mine."
Bader, the former Ultimate Fighter winner, dropped to 15-4.
