The Redskins add depth at a position of need and fill a roster spot vacated by Wednesday's release of Devery Henderson. The Redskins added depth to the inside linebacker position Thursday morning and announced the signing of former Arizona Cardinal Quan Sturdivant. Sturdivant was a sixth-round pick out of North Carolina in 2011 but was cut by the Cardinals during camp the following year. Since then he had stints with the UFL's Sacramento Mountain Lions and the Kansas City Chiefs practice squad. He has yet to play a regular-season snap in the NFL.
