Johnson Leaves Game After Fouling Ball Off His Knee

For the second time this spring Nick Johnson was forced out a game due to an injury, but luckily it doesn't seem to be anything major. Here's an update from Chad Jennings:

Nick Johnson has a bruised right knee. The Yankees have labeled him, day-to-day. No diagnostic tests were performed.

While it's not a major injury, we're already getting a dose of how fragile Johnson is. I'm doubting his ability to make it through the season healthy more and more with each passing day.
