Yankees manager Joe Girardi said that there was worry that Posada might have fractured a bone in his foot after fouling a ball off himself in the fifth inning of New York's 6-5 victory over the Angels at Angel Stadium on Tuesday.
"There is some concern about those toes," Girardi said. "Those bones are all so small down there. You worry anytime a guy hits a ball off his foot."
Posada waved Girardi and the team's medical staff off repeatedly and stayed in the game, making a strong throw to second base in the ninth inning to gun down Reggie Willits attempting to steal representing the tying run.
"Sometimes adrenaline keeps you in the game," Girardi said.
Posada reported to Angel Stadium for Wednesday's matinee against the Angels, but was quickly sent for precautionary examinations on his foot, which turned black and blue overnight. Posada did not speak to reporters before the game.
The news should be especially welcome for Posada, 38, who is batting .283 with 22 home runs and 79 RBIs in 106 games and should be a prominent candidate in the Comeback Player of the Year voting after missing most of last season due to injury.
Summing up a rather unorthodox lineup, Girardi said that the Yankees were "beat up" for Wednesday's game. Nick Swisher is day-to-day after fouling a ball off his right knee, but is considered available to enter the game.
Girardi said that he also wanted to rest Alex Rodriguez after he played a lengthy game on Tuesday, spotting him extra time off effectively with an off-day scheduled for Thursday as the Yankees return to New York and open a three-game series with the Red Sox on Friday.
