The worst injury on Sunday was the knee injury to rookie SS Morgan Burnett. From Mike McCarthy:
Morgan has a knee sprain. We’re going to go through a normal process; we’re going to have to do some more testing...
Nick Barnett had the wrist sprain and he did return.
Right now, I'm worried about Burnett. We'll have to see what we read about him this week. If it does become a problem, S Derrick Martin replaced him on Sunday, and he would be his likely replacement until SS Atari Bigby returns in a couple weeks.
It doesn't seem like the injured wrist will be a problem for Barnett.
