Jacoby Ellsbury has been dealing with right calf tightness, causing him to sit out for the past several days. As of Tuesday, he still felt it "a little bit" while going through his workout. He won't be traveling with the team on Wednesday, and probably won't play Thursday against the Red Sox. Joe Girardi said Ellsbury won't be back in a game until a day or two after he doesn't feel any tightness at all.
Scott Sizemore was shut down a couple of days ago with tightness in his right quad. He said that his knees are feeling fine, and that the quad isn't an issue. He took batting practice on Tuesday, and he's expected to return to games in the next few days.
Brendan Ryan hasn't played since March 7th, when he started to experience a lower back/oblique issue. He took batting practice Monday, and went through a full workout on Tuesday. The plan is for him to return to games Thursday night when the Yankees travel to the Red Sox.
Tyler Austin was able to take batting practice outside on Monday, for the first time during spring training. He has reported that his wrist is progressing, and he might make it into a game in the next couple of days.
