Jeter and Giambi should be fine - you know that Jeter will get back in there and play, and Phillips is a decent fielding first baseman, so Giambi can return to the DH while he's injured.

Damon I'm worried about, just because he would be yet another outfielder, and he's been a great leadoff man for the Yanks, who have sorely needed one for the last couple of years. Hopefully with the days off or DH'ing, we can keep a young guy like Thompson or Reese up to play the outfield and spell Damon.
