Derek Jeter left Wednesday night's New York Yankees-Detroit Tigers game after 7½ innings and it is not sure whether he will be able to play in Thursday afternoon's series finale.And yet, Jeter insists he is not injured, can't -- or won't -- say when whatever it is that happened to him actually happened, and couldn't even explain how his manager knew he needed to come out of the game."You'll have to ask him," Jeter said.
