Derek Jeter is out for the rest of the postseason after fracturing his ankle during Game 1 of the American League Championship Series on Saturday night.

After the Yankees gave up the lead in the 12th inning, Jeter ranged to his left on a ground ball, then went into a roll.

He stayed down, and when the trainer and manager Joe Girardi helped him off the field, he put absolutely no weight on his left leg.

Jayson Nix came into the game, which the Yankees eventually lost 6-4. Eduardo Nuñez is not on the Yankees' active roster, though the Yankees will make a roster move before Game 2.

Jeter had been struggling with a foot injury after fouling a ball off his right foot earlier in the playoffs. Girardi said in the post-game press conference that the normal recovery time for this kind of ankle injury is at least three months but it did not appear to be "career-threatening."
