Jefferson is off to a great start to training camp, strengthening his case for the third spot on the depth chart, according to Nick Baumgardner and Chris Burke of The Athletic.
Jefferson finished the second week of training camp in the driver's seat for the No. 3 role, ahead of Dedrick Mills, Michael Warren and Godwin Igwebuike. With lead back D'Andre Swift (groin) absent from Saturday's intrasquad scrimmage, Jamaal Williams worked with the first-team offense while Jefferson repped with the second-stringers, per Evan Petzold of the Detroit Free Press. The rookie seventh-round pick figures to make his NFL debut Friday night in Detroit's preseason opener against Buffalo.
