"You know how conservative I am," Girardi said. "So if it was something, he wouldn't have played."
Jeter -- who fumbled a ground ball in the second inning, causing a run to score -- was removed from the game at inning's end.
"That ball just got by him," Girardi said, "but it didn't crack the nail."
In the visitors' clubhouse afterward, Jeter had the pinky finger wrapped up to the knuckle. As he sat at a table in the middle of the room, a reporter asked Jeter if he was OK, and he said, "Yes, sir."
Yet Jeter clearly didn't want to address the issue again. As Jeter was leaving the clubhouse, another reporter asked him if the finger felt OK, and he replied, "Yep." The reporter thanked him, and Jeter said, "I didn't even hear what you were saying."
After he left the clubhouse, Jeter spent several minutes signing autographs for some of the many Yankees fans among the 32,229 who attended the game at Dolphin Stadium.
The Yankees will have a short workout at Yankee Stadium on Sunday, then open the regular season on Monday against the Blue Jays. Girardi sounded as if Jeter will be in the starting lineup against Toronto.
