Armah signed with Washington's practice squad Thursday, Nicki Jhabvala of The Washington Post reports.
Armah has longstanding connections with coach Ron Rivera, who was coaching the Panthers when they drafted the fullback in 2017. While he's more of a blocker than a runner, Armah could get an opportunity with the main roster if the injuries to Antonio Gibson (shin) or J.D. McKissic (concussion) keep either running back out of game action.
