General manager Brian Cashman previously mentioned Sept. 27 in Toronto as a potential return date for Teixeira from his Grade 1 left calf strain, but Teixeira said there is no specific timetable after an earlier attempt to rush back caused him to miss the past 10 games, including Thursday's.
"I don't want to put any timetable on it, because we tried to do that last time and it put unwanted pressure on everybody," Teixeira said. "We all wanted me to be back as soon as possible and I wasn't, I wasn't ready. I'm going to take it day by day, and when the doctors tell me I'm clear, when the trainers tell me I'm clear, when the strength coach and baseball people all tell me that I'm normal and running fine, then I'll be out there playing."
Teixeira is mostly just receiving treatment at this point, with some workouts in a pool, he said.
The Yankees are not being overly careful with their first baseman, according to manager Joe Girardi, simply attempting to ensure he does not suffer another setback that might keep him out of potential playoff action.
"It's something we have to heal. I don't think it's a matter of taking our time," Girardi said. "It's something that we have to make sure is healed, because we don't want it to happen again."
Swelling, tightness and soreness are immediately evident just touching his left calf, Teixeira said, although he has not suffered any setbacks since he last appeared Sept. 8 against the Orioles. That was his only game back after he missed 10 games upon suffering the injury running the bases Aug. 27 against Toronto.
He is traveling to the Yankees' facility in Tampa to simulate game action, although he would like to appear in a few games in New York before the playoffs begin, assuming the Yankees qualify.
"Just being in game situations where I leg out a double, I dive in the hole on a ground ball and run to first base -- those are things I need to do in a game situation," Teixeira said. "We can't try that out in a playoff game and have me blow out right away. That wouldn't be good for anybody."
