When Derek Jeter goes down, he doesn't often stay down.

But that's what happened Saturday night late in the Yankees' 6-4 loss to the Detroit Tigers in Game 1 of the American League Championship Series.

As New York tried to stop a Detroit rally in extra innings, Jeter ranged across short to make a play on a grounder, then appeared to suddenly trip. He rolled into the dirt then weakly flipped the ball back to second baseman Robinson Cano before remaining on the ground, clearly in pain.

Trainer Steve Donahue and manager Joe Girardi quickly came out to see Jeter, and moments later they were helping the shortstop off the field, with Jeter not putting any weight on his legs.

An X-ray revealed a crack in Jeter's left ankle, an injury even the Yankees captain won't be allowed to play through. It's the same ankle where Jeter has been battling chronic pain in recent weeks, with the injury flaring up after Jeter batted a foul ball off his left foot in the division series against the Orioles.
