This isn’t surprising, but Kevin Youkilis will go for an MRI on his back tomorrow. He missed about a week with a stiff back before returning the lineup yesterday, but the problem popped up again and he was unable to play this afternoon. If he needs to go on the DL — they can’t backdate it to last weekend because he played yesterday — I would think David Adams or Corban Joseph are the call-up candidates. Joseph is on the 40-man and that could give him a leg up. Let’s see how the MRI goes before worrying about that.
