NEW YORK—Yankees captain Derek Jeter broke his left ankle and is out for the rest of the postseason.

Three innings after Raul Ibanez sent the 47,122 in Yankee Stadium into a frenzy with a tying two-run homer, the durable New York shortstop silenced the crowd when he went down and didn't get up after making a diving stop on Jhonny Peralta's grounder in the 12th inning.

From delirium to dread in a flash.

Jeter dived to his left for the sharp grounder and winced in pain as he flipped the ball toward second base. He then rolled onto his stomach, and a collective gasp was heard when he stayed down.

Jeter remained on his side, rolling slightly, as trainer Steve Donahue and manager Joe Girardi checked him out. He was helped up, and he put an arm around Girardi and Donahue. They coaxed him off the field with Jeter not moving his left leg as chants of "Derek Jeter!" rang out.

"You can see the disappointment in his face," Girardi said after the Yankees' 6-4 loss.

Girardi said the injury won't jeopardize Jeter's career. But the recovery will be about three months.

If the Yankees are going to go deep in the postseason they will have to do it without their durable star for the first time in 16 years.

The Yankees will activate Eduardo Nunez before Game 2 of the series on Sunday.
