Toston spent the preseason with the Jaguars before being waived on final cuts. He was re-signed last week and returned two kickoffs for 49 yards against Green Bay. He was waived Tuesday, replaced on the roster by Marshall.
Maybe more pressing for Jacksonville is the health of its secondary. Safety Dwight Lowery (ankle) has been ruled out against the Lions and starting cornerbacks Derek Cox (back) and Rashean Mathis (groin) sat out practice Thursday. Cox and Mathis were limited Wednesday, but it's unclear if they had setbacks.
