Powers is doubtful to return to Sunday's contest at San Francisco due to a calf injury, Darren Urban of the Cardinals' official site reports.

EDGE Analysis

Powers entered the contest with 40 tackles (35 solo), one interception, and one sack on the season. However, he tallied just two solo tackles before departing the game. While he's unlikely to return to the field Sunday, his progress will be watched closely this week to see if he'll play next Sunday in St. Louis.
