Brad Childress just said it during his Monday news conference. Peterson's LCL is torn, but the rest of the knee looks to be okay. No damage to the ACL, PCL, MCL, or meniscus or anything else.
The good news is that it looks like Peterson is NOT going to need surgery, but the Vikings are still unsure how long he's going to be out.
According to Childress, Peterson's tear is graded as a "2+." So, he's going to be out for a while. At least a few weeks, to be sure. Childress said that if this had happen to a lineman, they'd be braced up and out there on the field. Obviously this is a little bit different.
We'll get more into the ramifications of this later on this evening. I just wanted to make sure the info got out there for now.
