When Mark Teixeira's left calf underwent an MRI exam Sept. 10, the prognosis was that he would be out 10 to 14 days.

However, that's not going to happen. The 10th day is today and the 14th is Sunday. Now, the Yankees are looking at a four-game series in Toronto (Sept. 27-30) to get back their switch-hitting first baseman.

"I wouldn't be surprised if it took that long,'' manager Joe Girardi said. "As of Sunday he still had soreness. It's not progressing as quickly as we would like. We have to get him right.''

Teixeira exited a game on Aug. 27 with a calf injury. He missed 10 games, returned for one on Sept. 8 in Baltimore and re-injured the leg on a head-first slide into first base that ended a 5-4 loss.
