Per the New York Jets:
Rookie CB Dexter McDougle suffered a torn ACL (left knee) today at practice.— New York Jets (@nyjets) August 10, 2014
It doesn't sound like Dee Milliner's ankle injury is all that bad, perhaps just a rolled ankle. McDougle apparently felt a sharp pain in his knee before walking off, although this is obviously awful news for the rookie cornerback who was finally healthy and had a strong game against the Indianapolis Colts. I suspect we'll be seeing a lot more of Darrin Walls now. We'll have more about this when we get some more detail from the team.
