Head coach Bruce Arians said Monday that Powers will man the nickel cornerback spot previously held by Tyrann Mathieu (knee) for the rest of the season, Darren Urban of the Cardinals' official site reports.

EDGE Analysis

Mathieu picked off his fifth pass of the season Sunday in Philadelphia, yet the dynamic one also suffered a torn ACL on the same play. Because Powers has logged most of his snaps on the outside this season, he might face a slight learning curve in Mathieu's stead. However, Powers' steadiness (nearly four tackles per game and five interceptions in 43 career contests with the Cardinals) should serve him will in the new role.
