Bears' Roschon Johnson: Not practicing yet

Johnson (concussion) was a non-participant at Wednesday's practice.

Johnson is six days removed from suffering a concussion last Thursday in Washington, so his inability to practice yet in any fashion isn't a promising early sign for his chances of playing Sunday against the Vikings. All of Johnson, Khalil Herbert (ankle) and Travis Homer (hamstring) sat out practice Wednesday, leaving D'Onta Foreman, Darrynton Evans and Khari Blasingame as the Bears' current healthy backfield options.
