Teixeira said that he felt more discomfort in his left calf when he raced to first base in the ninth inning of the Yankees' 5-4 loss to the Orioles and does not expect to play in Sunday's series finale against Baltimore.
"We'll see how it plays tomorrow, but I'm probably not going to be there tomorrow," Teixeira said. "I don't know. I've still got a little adrenaline going through, I'm still pretty upset about what happened out there, but we'll see in the morning."
Teixeira said he told head athletic trainer Steve Donohue that his calf "doesn't feel right."
"It was tight all night. I never really had to put it into second gear," Teixeira said. "I could kind of cruise in on that [first-inning] double, and I didn't need to run after that, really.
"When I was on base, it was OK, but I kind of knew in the back of my mind if I had to put it in that second gear it might get a little dicey. And when I did, it got pretty tight."
Teixeira said that he hopes this does not mean he has to start over in his rehab from the Grade 1 strain of his calf, which already cost him 10 games before he returned to the lineup on Saturday.
"If you wait until you're 100 percent to play, you might never play, really," Teixeira said. "That's just the way sports is. My whole career, I've played through things. I've been able to protect certain things, and when you need to take a couple of days off, you do. I took 10 games off and I felt like it was time to test it out. I felt like I was good enough in the work I had been doing."
