Will Johnson Injury: Doesn't practice Thursday

Johnson (back) did not participate in Thursday's practice, Zach Gershman of the Cardinals' official site reports.

A back injury prevented Johnson from playing against the Seahawks in Week 10, and he's opened Week 11 prep with back-to-back DNPs. The rookie second-rounder would need to practice Friday in at least a limited capacity in order to have a realistic chance of playing Sunday against the 49ers.
