Jim Edmonds is back - Stern was sent down to make room
Craig Counsell has a "minor quadriceps injury"
Joe Inglett's left ankle is still sprained
Todd Coffey hurt his thumb WHILE BATTING and was unavailable in yesterday's game
Doug Davis had additional heart problems a couple of days ago, so can be expected to be out for a bit longer
I haven't heard an update on Gregg Zaun recently, but last I heard, he was going to attempt to rehab but was in severe pain.
