Mark Teixeira has braced for the reality that he will miss most of the remaining Yankees' regular-season schedule, but he does not regret pushing his strained left calf in an attempt to get back into the lineup.

"I'm obviously disappointed," Teixeira said. "I don't want to miss any time, but it is what it is. I can't really change it, so we'll just keep working hard and try to get out there as soon as possible."

After sitting out for 10 games, Teixeira tried his luck in the lineup and reinjured his calf trying to beat out a ninth-inning double play at first base in Saturday's 5-4 loss to the Orioles.

An MRI exam taken on Monday in New York revealed that Teixeira had irritated his original Grade 1 strain, and the Yankees said that Teixeira is now forecast to miss a minimum of 10-14 additional days.
