Anytime a running back has an injury below the waist, it is reason for concern.

Portis is obviously a tough guy and a fierce competitor, so he will play through pain no matter what part of his body is affected. But if he has a real injury - as opposed to a really bad bcruise that causes a lot of pain but nothing more than that - in his hip, it is a bad omen for a running back.
