James Cook got hurt in this game. He's seems to be fine, but just one of those reminders that if James Cook was to go down, Ray Davis would be the guy.

Cook got hurt in Week 8 but seems fine; Ray Davis is the key handcuff.

James Cook suffered an injury during the Week 8 game against Minnesota but appears to be fine. This serves as a reminder of his injury risk and the contingency value of Ray Davis as his handcuff; if Cook were to go down, Ray Davis would become the lead back for Buffalo's offense.
