Tom Gordon is out for at least three months after tearing a muscle in his shoulder.
Jeff Kent fractured his wrist washing his truck and will probably miss most of April.
JD Drew has been having problems with his ankle. Normally nothing to worry about, but with Drew, you never know.
Ryan Anderson will once again miss the year with a possible tear in his left shoulder (not sure if that's the final diagnosis). Poor kid seems cursed.
Kris Benson is still out.
Bill Mueller underwent knee surgery.
Jason Schmidt has some sort of groin problem that will probably cause him to miss the beginning of the season. I still like him for this year, but he'll probably miss a couple weeks.
John Franco is likely to be out until May.
Former super-prospect Alex Escobar is out for the season.
Scott Elarton had shoulder surgery, but you wouldn't want him anyway.
Robb Nen suffered an as-yet undetermined foot injury. Probably no big deal, but worth keeping an eye on.
And Rick Ankiel added tendinitis to the list of reasons to be very careful when drafting him.
That's all I can think of off the top of my head - hope this helps!
