"Right away my friends called me and said, 'Guess what,'" Teixeira said. "But no matter what happens, whether I could have a title shot or not, I'm going to step into the octagon the same way. I'm going to go for the knockout. That's the way I fight.
"I'm going to push the pace. I'm going to try to control the octagon and finish the fight as fast as I can. It's not a matter of doing something different because I might have a title shot later. That's the way I fight."
Teixeira is excited to return to his home state of Brazil for his UFC Fight Night 28 bout against Bader.
"When I was fighting in Brazil, I was always thinking I would eventually get on a card in Belo Horizonte so I could fight in my home state, but I never got that opportunity," Teixeira told USA TODAY Sports and MMAjunkie.com. "Now I'm in the UFC, and I'm fighting in the main event here. It's going to be great. It's very exciting. I hope all the people will come to support me."
For Teixeira, he'll have four siblings in the crowd, but not his parents.
"My dad wanted to go, but my mom, she gets nervous," Teixeira said. "She doesn't watch the fights live. She records them watches them later. So my dad is just going to stay home and keep her happy."
