It is frustrating for everyone involved to see Chris Wilcox have yet another injury setback. Thankfully he won't require surgery. While an original report stated that he would be out 3-4 weeks, apparently they aren't sure about that anymore.

There's currently no timetable for Wilcox to return, though he will be re-evaluated by doctors next Tuesday, and the results of that meeting could produce a target date. In the meantime, he's sporting a small gray brace that anchors the thumb in place.
Get well soon Chris.
