EDGE Analysis

Powers was in considerable pain after coming off the field Sunday, spurring head coach Bruce Arians to hope that the cornerback hadn't injured his Achilles. After an evaluation, though, Powers has been diagnosed with a strained calf and is considered day-to-day. Ultimately, his activity level in upcoming practices will forecast whether he'll suit up in Week 13 at St. Louis.
