Peterson's knee is sore following Sunday's game against the Falcons, but he does not have any structural damage, according to coach Bruce Arians, Darren Urban of Azcardinals.com reports.

EDGE Analysis

Peterson was noticeably gimpy during portions of Sunday's contest, but he valiantly still limited opposing wideout Julio Jones to just four catches and 35 yards. With some soreness to contend with to start this week, it's entirely possible that Peterson's practice involvement is managed over the course of this week, but the fact that he doesn't have any structural damage bodes well for him being able to suit up Sunday against the Redskins.
