Somers considers Peterson to be closer to probable than questionable with head coach Ken Whisenhunt having a conservative approach to his injury report. Fellow secondary members Rashad Johnson (thigh) and Adrian Wilson are also questionable but Somers believe they'll be on the field as well.
Cardinals fans have to be hoping that Somers is correct in his analysis as Peterson is expected to match up against big-play machine Brandon Lloyd.
Peterson has yet to miss a game in his young NFL career after setting a standard of playing through injuries during his rookie campaign. The 6'1", 219-pound defensive back opened the season with a strong showing against the Seattle Seahawks last week, holding Sidney Rice to just 36 yards on four receptions.
