Jeter is believed to have suffered the injury batting in the fourth inning against Minnesota right-hander Nick Blackburn. He was hobbled briefly but remained in the game, stroking hits in his next three at-bats. Girardi lifted Jeter for pinch-runner Melky Cabrera in the ninth inning representing the go-ahead run with Alex Rodriguez batting.
"I think he'll play tomorrow," Girardi said after the game. "I just felt that if Alex hit a ball in the gap, I wasn't sure that he could score at that point. He's icing, X-rays are negative and we expect him to play tomorrow. We'll see."
Jeter, 34, is batting .284 with seven home runs and 57 RBIs in 113 games for New York this season. Girardi said he was not surprised that Jeter would not want to miss a start.
"He's always been a tough kid -- I guess maybe he's not a kid anymore," Girardi said.
