Injury impact on McFadden's free agency

I almost wrote a note last week about how the Oakland Raiders' Darren McFadden had actually made it through three games without suffering an injury. Considering his lengthy injury history, that story itself would have been newsworthy. Instead, I figured I'd wait until he got past the quarter pole before drawing any conclusions. Well, here we are, one week later, and to no one's surprise, Run-DMC is battling an injury. This one appears to be relatively mild -- a hamstring injury -- but it was bad enough to keep him from returning to action. He finished the day with just 29 yards on five carries.
